What's Not To Love?
- Familiarity: I've put it through the wringer
A great sleeping bag for us taller/bigger folks who want a roomier version of your standard mummy bag. This is my second MegaLite bag; the first I "lent" to my girlfriend two years ago when we first went backpacking together and I never got it back. I finally broke down and got another MegaLite so she wouldn't be the only one with a top-end sleeping bag. This bag is so warm that 80% of the time I use it as a quilt and am perfectly comfortable - and I'm not an especially warm sleeper. Compare the loft of this bag to other supposed 30-degree bags and it's obvious the MegaLite has more (better?) down. Great loft in this bag. In my mind it's a high-quality, life-time investment! (FWIW, the girlfriend who borrowed my MegaLite is now my wife and I like to think that me lending her my pride-and-joy all those years ago had something to do with that. ;-)
Best Sleeping Bag Brand, Period!
- Familiarity: I've put it through the wringer
I have owned my Megalite for 10 years. It is the best piece of camping equipment I own. It is incredibly light, packs to the size of a cantaloupe and is even better than advertised from a temperature rating standpoint. This summer I sold mine to a friend and purchase another one right away.
My Dream Bag
- Familiarity: I've put it through the wringer
I loved this thing so much, i ended up getting the kodiak as well for colder trips! I've now had this bag for 5 years though, and I've had no problems at all. I may send it in for some extra stuffing soon, but that's to be expected after close to 6 years of pretty constant use! I didn't really realize how awesome WM is though until I went to shop for a colder weather bag a couple years ago. I actually tried a few other companies over several months (trying to avoid the high WM price tag), but I ended up coming back to this awesome bag company in the end. WM makes a more comfortable bag than other companies with plenty of wiggle room, and they rate their bags' temperatures more conservatively than other companies, which means more warmth! You really can't beat their quality! ...Also, I can zip both bags together with no problems (since one is left, the other right), even though they are different links.
Perfect choice to fit my needs
Fwiw, I received my 6' regular Megalite today so, of course, I gave it the once over. . While I didn't inspect it minutely, I saw no noticeable defects in workmanship. The zipper operated smoothly without snags. The material felt nice on the skin. I then tried it on for size. Right now I'm 6'10.5" and 195 lbs with a 42" chest. I wore a base layer with my Golite synthetic vest and Zpacks beanie. I easily fit in the bag at the shoulders and chest with the vest on. I could cross my arms over my chest or leave them lengthwise next to my torso without constriction. The bag also easily fit lengthwise, I had no issues wearing my beanie in the hood, and the draft collar seemed to fit well. In fact it felt like I had about 6" left in the footbox where I could place damp clothing to dry or water bottles without sacrificing foot area. The footbox felt pretty roomy as well without the need to curl my toes. The stuff sack weighed 1.4 oz on my scale. The bag in the sack was 26 oz exactly meaning the bag weighed 24.6 oz. on its own. Admittedly the bag is expensive but I already have confidence it will give me the protection I need while allowing me to manage a lightweight pack. All in all, I know I made the right choice for my needs. Lastly, the purchase supports American workers instead of Chinese. I like that fact a lot.
customize your down by sending it in.
- Familiarity: I've put it through the wringer
this is a high quality sleeping bag if you do buy it and find that you are cold with your 30 degree rating and don't think you are warm enough western mountaineering is a solid company send the bag to them ask them to stuff your bag with a bit of extra down and boost your temp on your bag. i love this bag mainly cause it is so light and with my compression sac i can squeeze this guy in my small light day pack and still have room for the rest of my gear. i bought this cause i was cutting weight from my pack and got all new gear with super light wt in mind. i say get it like i said if it not as warm as you hoped send it in and get a boost of down.
- Familiarity: I returned this product before using it
Loved the bag in terms of workmanship and materials, but I returned it when I decided that a 20 degree three season bag and a 40 degree summer bag better fit my needs. I replaced this with a WM Alpinlite and a WM Mitylite.
WM Megalite wonderbag!
I have been using my 6' mega for 2 yrs and am so pleased with how the temp rating is right on but I have easily pushed the temp rating by wearing long unders. I have put on my down sweater inside it and been too warm so Im not sure where the bottom temp is on that combo.You can only do that because of the generous cut. Buy this bag and feel like a very smart and patriotic outdoorsperson!
WM Megalite is for real
- Familiarity: I've used it once or twice and have initial impressions
This bag is just great. I am 6'2 185 lbs and bought the long size. I am a side sleeper and prefer space inside of my bag; this bag fits my needs perfectly. Lofty, warm, light, and smooth are the four words that sum up its features. I can't believe a bag this spacious actually fits into the included XS stuff sac. I especially love the smooth inside/outside face material, it just feels very soothing to the touch, unlike the Montbell u.l.'s tissue like material. Few people talked about the function of a smooth face material on a sleeping bag, but the smoothness of the inner surface lends itself to allow easier tumbling and turning, without taking the bag with you.
My wife and I can even use it unzipped as a comforter, and achieve decent warmth and comfort. It also shows minimum down leakage, which is a serious problem in other bags that I have owned. This is one piece of luxurious equipment that I can honestly say well worth the money.
- Familiarity: I've used it once or twice and have initial impressions
This is my first WM bag and I'm hooked. Just took it on a 2 night backpacking trip. Super lightweight & compact. I'm a woman, 5'2 and the 5'6" is perfect. It is roomy in the shoulders good if you move around alot at night and/or for warmer temps but not efficient in temps below 40 (I stuffed my extra clothes in the space to make it work in upper 30's) I do like the bag, but because of the roominess, this will be my warmer weather bag and I'll probably get the Apache for more efficiency in cold wx.
Simply the best!
I have purchased 4 WM bags over the years and have steered several friends to them as well. They are simply the best sleeping bags made. Superior quality and performance in every way. They are a work of art. I use the Megalite for most of my backpacking, It's just right for 3 season use.
Received mine last week and took off for two nights. It was 38f and damp as is usual in the Sierras this time of year. I was totally warm and dry.
I have a MontBell 32f that cost $40 less and I was freezing last month. Big deal..save $40 for Chinese junk. I also had another high end brand 32f bag...same thing..Chinese junk.
I also have an Alpinlite. It is too much unless around or below 32f. WM bags are the only ones with real temp ratings.
Spent two weeks sleeping comfortably in 30 degree weather. I never once felt the chills and most nights never even had to zip up all the way. Granted, I am a very warm sleeper, but I would take this bag down to 20 degrees with very little problems. Western Mountaineering makes a no frills (and no chills) bag that will last a lifetime as long as you take care of it like it takes care of you. The price is steep, but it might be the last bag you ever buy (or, if you are like me, just the first in the entire WM lineup). Add to all that the fact that it is Made in America and you should feel very warm about your WM purchase.
This bag is undeniable.
Handmade in the USA
Perfection? I've had my megalite for three years now, and I couldn't be happier. I've used on everything from multi-day backpacking trips, to multi-day cycling trips and three season recreational camping. I've never had a problem with it, and don't think I ever will. I purchased mine at another store, and they only had the 6'6" model, so I'm swimming in it as I'm only 5'4", but that doesn't effect the performance. Overall, I don't plan on buying another bag from any company except WM, superior quality and pack-ability.
Western Mountaineering bags are sweet
One of the biggest mistakes of my life was trading my 30 degree bag for a 35 degree. But bags are exceptional and both have accompanied me on Appalachian Trail thru-hikes, but I miss the full zipper feature that the Western Mountaineering MegaLite 30 degree bag has. I sleep very warm so my 30 degree bag with a silk liner keeps me warm even when the temperature got in the 20's. On warmer nights I would unzip it and use my bag as a quilt. It compresses down nicely and recovers it's loft quickly. The life time warranty is a great piece of mind, but I have yet to have any problems with any of my western mountaineering bags..
Best bags in the industry
I love these bags. I have the Summerlite which is very similar to this bag but not as wide. WM uses the best down available, their testing of down usually exceeds a 900 and sometimes 930 fill rating. They base the warmth of their sleeping bags on an 850 fill which is why their bags are always warmer than what they say. My bag is rated at 32 degrees but it feels more like a 25 degree bag. If you haven't experienced a WM bag, then you haven't experienced a good nights rest in the BC.
This bag is well worth the hefty $$
For warmer weather and extended hikes, there is not a better bag. Used this in the warm weather portions of my 06 and 08 AT hikes and it never let me down. Very light and even as you drop below the rating on those colder nights, a simple base layer and socks kept me warm. I switched from using the Marmot Pounder simply because I experienced an internal condensation issue with the pounder (although I admit I was pushing the pounder past its design). The price tag is hefty with this bag so you should really be needing the warmth/weight ratio to justify the price. I have used this bag for no less then 9 months of hard use on shelter floors and it is still holding up well. For me, it was well worth the price tag (I think I paid around $225 in 06) It will be my bag of choice after Damascus in my upcomming 2010 AT hike.
Western Mountaineering is my hero.
I researched and tried out probably twenty 3-season sleeping bags before I found my precioussssss. I'm a warm sleeper, so this is a FULL 3-season bag for me at 30 degrees. Honestly Western is conservative in their temp ratings anyway. Everything about the MegaLite is top notch. The loft amazes me for being so light and compressible, the zipper NEVER snags, and I even like the burgundy color of it (my bag is not straight purple like the picture above, it's burgundy). It has a highly water-resistant shell and with a waterproof compression bag (I suggest Sea to Summit's eVENT) you will have a supremely light, tiny bundle of down goodness you never have to worry about getting wet.What else can I say? Sometimes I pull this baby out of my closet just to look at it cuz it's so beautiful! This is the perfect bag, and my absolute favorite piece of gear.
Is there a way to attach it to my sleeping pad?
At night I always turn around and find myself off the pad
Unfortunately this sleeping bag does not have a way to attach a sleeping pad. I would recommend checking out the Therm-a-Rest ProLite 4 Sleeping Pad (CAS003Z). It features a sticky-dot non-slip surface that ensures your mattress stays put for a full night's sleep.
I need more of a summer sleeping bag used for many activities. I am picking between SummerLite or MegaLite where I like addition of top colar on MegaLite and additional down BUT I am not sure about the size. It is wider than SummerLite.
How can I know if this will be to big in shoulder area or not. Usually i sleep in base layer.
What is the circumference of your shoulders? Do you move a lot when you sleep? I mean the Megalite will be more comfortable because you have more room but, you sacrifice a little weight. I'd say if you move around a lot go with the Megalite, if you can sleep still on your back the Summer Lite is a good option.
Feel free to hit me up at email@example.com or 801-736-6398.
Hi, just wondering what the actual length of this bag is in the Long size. I'm just over the height limit at 6'7" and wonder if the length would be too short for me. All other measurements are present except length on their site as well. Thanks
Hey there, Leta here with Western Mountaineering. Shoot, this is a tough one. You really need a semi rectangular option, and Western Mountaineering does make a bag that I think would work: a 6'6" Alder at 25 degrees. It's semi rectangular, no hood, which is what you would need. The only 7'0" options we have are starting at 15 degrees and colder. The Gear Heads at Backcountry.com are awesome about special orders. They will take good care of you!
Hope this was helpful,
Sleeping bag liners and pads to recommend. I just got my 6'-6" Megalite and am trying to figure out what liner and pad would work best with this bag? I am a side sleeper! Thanks, Ben
There are a whole bunch of options. How important is weight to you? What type of R-value are you looking for in the sleeping pad? What type of trips / area will you be taking this set up to.
Feel free to email directly and I can work with you 1-on-1
Hello Does the megalight open fully into...
Does the megalight open fully into a blanket like the terralite?
Or does it zip down one side to the feet, which remain enclosed?
The latter of the two possibilities: this bag zips down one side to the feet, which remain enclosed.
Hope this helps.

Do you guys every plan on getting the 6' version in stock??
Your best bet for a quick answer to stock questions will be to initiate a chat with a BC rep using the link at the top of the page. Best of luck!

Where are the 6 ft west mountaineering bags.every model I look at only has 5-6 and 6-6.
The bags are so popular that all of the normal sizes are out of stock right now. Check with a Backcountry rep in chat or by email or phone to see if they have an ETA on new orders.

I need to make one more check before investing in two of these Megalite bags.
Assuming I get a Long LZ and a Reg RZ, can i couple/mate/zip two megalite bags together?
They should zip together, the only thing to consider is one zipper may be slightly longer. But these are the best bags out there, and made in USA. You wont be disappointed.
I have this bag and a longer WM Kodiak, and although the temps of the bags are very different, they zip together without a problem! I've also noticed that a 6ft person can make due pretty well without feeling cramped in the 5'6" bag!
I wondering about this one or the Highlite....
I wondering about this one or the Highlite. I'm gonna use it as an ultarlite trekking bag for sleeping indoor or in a tent. For colder conditions I have an MH Phantom 15. Is there any reason to get this one over the Highlite?
With the Megalite, you can shift the down around to load up in cold spots and have a bit more circumference, it has a draft collar and full length draft tube, wider cut and a full-zip, but the Highlite is less expensive, narrower, lighter, different material, about the same stuff size, rated 5 degrees higher. Comparing specs side by side, both sound like they would suit you just fine. Nothing that Western Mountaineering makes will disappoint if you appreciate quality and know your needs. That said, my personal preference would be the Megalite, if for no other reason than the extra room.
Phil nailed the answer. Megalit is my call too!
Yeah...the collar and if you get caught out at 28f.
Hey guys i know the official packsize is...
Hey guys i know the official packsize is listed but is that compressed? or just stuffed? ALSO does the bag compress well i want a bag that goes down small =) Cheers!
The pack size listed is usually uncompressed. Down bags, especially WM, compress really well.
WM bags come with a regular stuff sac and so the compressed size listed is in a regular stuff sac. I've seen the Megalite compress to a little larger than the size of a softball before... Great stuff!
this bag comes with a large storage sack, it also comes with an XS 7 X 13 inch regular stuff sack. However, if you want it smaller than that, I recommend the sea to summit event compression dry sack. XS is 6X14 inch non compressed.
can i order this bag with 2 oz of...
can i order this bag with 2 oz of overfill?
Backcountry cannot ship it that way. You can order the bag and once you receive it, send it in to Western for an overfill. I believe it runs about 60 bucks for that.
Then get it from the factory.
This question actually pertains to the WM...
This question actually pertains to the WM Summerlite, but the answer should be the same for the Megalite, thus I'm asking it here. I was told by a different dealer that a 6' RH zip and a 5'6" LH zip bags "cannot zip together". Does this mean that they physically cannot zip together, or just that there will be a little extra zipper on the longer bag?
There will just be a little extra zipper... I zip the mega into a WM Kodiak all the time! 1 is 5'6", the other is 6', and the temps are noticeably different depending on the side you end up on (only noticeable on a cold cold night though)... I have also noticed that a 6'2" person can sleep in the 5'6" Mega side without issues though, which is great if one person is warmer blooded than the other.
Hey, I'm looking at a 30 degree, lightweight...
Hey, I'm looking at a 30 degree, lightweight bag for summer, late spring and early fall in Idaho. I am having a lot of trouble deciding between the Marmot Hydrogen, MontBell U.L. Super Stretch Hugger #3 and the Western Mountaineering MegaLite. Anyone want to give their two cents to help me decide?
Here's my two cents:
Both Marmot & MontBell make excellent bags. I've used both but when it came to putting my money on the line, Western Mountaineering won hands down for these two main reasons:
1. WM bags have the greatest warmth to weight ratio. In other words, their ten degree bag weighs the same as the competitions twenty degree bag.
2. All Western Mountaineering products are made in the USA from the most state-of-the-art materials available.
I have owned two WM bags for many years & my answer is strictly a personal choice & preference.
I'm really intrigued by the continuous...
I'm really intrigued by the continuous baffle construction. Any testimonies to how well people like this? Does the down shift much in the middle of the night? I'm used to opening my bag up to use as a down comforter on warmer nights, and am debating if I want to go with a continuous baffle or divided bag from WM.
Get the continuous baffle! Its far warmer for little more weight. Basically there is a bit of mesh between each section rather than being sown though.
I agree with Kurt. With a 4" loft bag like this, you don't have to worry much about down shifting (unless you sleep vertically like Batman). Go with the continuous baffle, the sewn through option creates cold spots where the bag is sewn, and is really only necessary when a bag has VERY little down in it (like the WM highlite). This bag has the perfect amount of down for its temp rating and I've never had any problems with down being in the wrong spot.
Continuous baffle construction is far superior than any sewn through option. Baffles aren't a negative, in fact he baffle gives the sleeper more options. Trust me, down will not move or shift during the night. I'm not even sure it would hinder batman all to much. You can make down shift if you want to, but it takes some significant effort. Sometimes I like to pack a little more on the sides so the top can breath a little bit better. If you just shake your bag a few times with the help of a friend, the down will settle back down evenly again and you're ready to go
I have one and love it. The advantage of the continuous baffle, is that you can shake the down to one side of the bag, Hint! move the down to the side that you are not going to compress with your body weight. Use a good quality pad (or two) and then you will have all of the down insulation where it will do the most good!
