Hello
Does the megalight open fully into a blanket like the terralite?
Or does it zip down one side to the feet, which remain enclosed?
Many thanks

The latter of the two possibilities: this bag zips down one side to the feet, which remain enclosed.
Hope this helps.

My Dream Bag

  • Gender: Female
  • 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.

Highest quality, but NOT a 30 degree bag

  • Familiarity: I've put it through the wringer

The build quality, the quality of the down that Western Mountaineering use (850 fill-power Goose Down), and the design itself are second to none. They are all handmade and usually made to order in northern California, which is a rarity these days. I bought the Megalite because I am extremely tall (6'6'') and broad shouldered, and I fit perfectly inside with room to spare. It packs down to the size of about two, 1 liter Nalgene bottles, and even smaller if you have a compression stuff sack. It weighs next to nothing. Everything else aside, this bag was simply not warm enough for its rating. I gave it 5 trips into the backcountry before I decided to send it back. During 4 out of 5 of those trips the temps did not dip below 40 degrees and I was still freezing, and I run EXTREMELY hot. I thought I would spring for a top class, ultralight piece of kit after twenty years with an old North Face Foxfire, but $420 is way too much to pay for something that does not keep you warm. In retrospect, if I was to buy another Western Mountaineering bag, I would buy the Alpinlite, but a bag this expensive is an extreme luxury. I'll stick with my old Foxfire for now.

Loved It

  • Gender: Male
  • 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

  • Gender: Male
  • 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.

Took the bag for an overnight in Zion NP, the low temp. was in the high 30s. With an uninsulated pad, still no problem at all. Even with all the extra space of the long bag, I didn't feel any cold spot the entire night. I do always wear a light insulated hoodie to protect my head and neck. I am comfortable taking this to its rating as is, and to 20s even high 10s with a good puffy jacket and pants (more than enough space for that in this bag).

Responded on

Just took the bag for another trip to 10000 ft. alpine snow.
Low was 29F and windy (inside a single wall tent, good air flow), still good. A little cold when side-sleep, but there's not a fault of this particular bag. Leaning against wife solved the problem. (Is there a side-sleeper's bag?)

Sweet bag

  • Gender: Female
  • 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.

Megalite

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.

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.

Responded on

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?
Thanks.

Responded on

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.

Responded on

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....

Posted on

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?

Responded on

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.

Responded on

Phil nailed the answer. Megalit is my call too!

Responded on

Yeah...the collar and if you get caught out at 28f.

Western Greatness

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.

Ya

This bag is undeniable.

Hey guys i know the official packsize is...

Posted on

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!

Best Answer Responded on

The pack size listed is usually uncompressed. Down bags, especially WM, compress really well.

Responded on

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!

Responded on

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.

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..
