ALPS Mountaineering Crescent Lake Sleeping Bag: 20 Degree Synthetic

Bought it to fill out the 20 degree spot in my low-budget collection. Great in milder conditions but it hasn't really held up well at temps below 30 though. Pretty much behaves like my MH Lamina (35 F), except bigger when packed.

I got this bag on a budget, this bag is great but could be better-draft tube internal pocket and zipper on the right instead the left.

Anyways, I have slept many nights in this bag and granted it is bulky and heavy I have gotten it to compress to half the size it is normally it's still a great piece. It does need "venting" I do not dare sleep on the couch with I wake up sweating every time. It does just fine on a pad where excess heat can dissipate freely. I LOVE how roomy this is I bought the wide version and even though at 5'6" 130lbs, I toss an turn a lot and this bag fit the bill. I have had it out in high 30's and tee shirt and shorts and does what it's supposed to do. Even bought the wife one. The other thing is that I've had to change the way I zip it up since there is no tube near the zipper if your not careful you'll snag it every time. But for the value I'm not too concerned. Most of the time I leave it open anyways. I did pair it with thermarest neo camper sv, it does hang over the sides (a couple inches) it covers the whole pad so I'm pleased.

So the takeaway from this review should be that for the money, you aren't going to find a better bag. Great for Car camping, but not super light or compact for backpacking.
I have camped comfortably into the mid 40's (f) in this bag and have no doubt that it will keep me comfy into the mid 30's (f) I have only used it a couple of times but am happy with my purchase and would gladly make the same decision again.

I love ALPS gear because of their quality and affordability. This is a great, warm sleeping bag, especially for the price. Would recommend.

quality bag. nice bright green color allows you to see it easier at night. warm as you would want it for 3 season camping. Zipper zips all the way up and you snuggle in there deep. not the most space efficient bag but it is warm.

Bought this for my wife for some summer camping trips, not very compact but she seemed to still enjoy it

Alps Mountaineering is amazing when it comes to quality gear for the person on a budget. This bag has kept me warm on numerous car camping adventures. It is comfortable and I feel like I have enough room to move around at night. If you are looking for a great sleeping bag for an amazing price, go for it!

Keeps me toasty in 45 degree weather, love how roomy it is. Definitely not a backpacking sack but a great vehicle camping sack. Silky texture. Seems like it'll last if stored in compression sack (sold separately). Happy especially at the $50 price I paid!!

This online store is the greatest. I was having some difficulties in determining shipping costs. The online chat service was so helpful and nice while helping me with my order. Thank you for your help, Backcountry!

looks good and feel good on my body. use for camping trip.

Took this bag with me on my two week road trip thinking it would be a big help throughout most of my cold destinations, and it did until the night I spent at the Campground in Black Canyon. In my Alps Mountaineering tent, sweats, wool socks, thermal sleeping pad, snow falling on my tent, sleeping bag zipped up and Velcro strapped all the way up and all I could think about was how cold my feet at back still were. This bag definitely did not stand up to those conditions. And it was about 34 degrees out. All other spots it was fine. Just don't take this bag out to snowy areas.

We took it on a car camping trip. It packs well and smaller than I thought, based on some other reviews here (although it is still suited for car camping). The night temperature was in the low 50s, so I slept with the bag open. It was comfortable. Looking forward to testing it in lower temps.

I'm 6'2" and this sleeping bag is the perfect size. Snug for warmth and not too tight. It's large for hiking but breaks down nicely to pack away for car camping. I haven't put it to the "cold night" (under 45 degrees) test yet.

This is a great bag for car camping and comes with a tough and sturdy stuff sack for storage. I used it in the desert in early spring in southern Nevada and it definitely kept me warm for 45 degree nights. I wouldn't recommend this for backpacking as it is pretty bulky/heavy.

I picked one of these up to have as a spare when friends come to visit. The bag is great for car camping or when packability/weight are not a huge issue. It shouldn't come as a huge surprise that this bag is on the heavier/bulkier end of things. You can backpack with it in a pinch, but it's going to take up a good bit of real estate in your pack. I have the regular size - it's quite generous in the chest/shoulders and fits me (albeit snugly) at 6'1". The 20 degree rating is maybe a little optimistic - this bag kept my friend comfy enough at around 30 degrees a couple nights ago but she said that was about the limit of how cold it would be good for.

Durability seems good so far and the fabric is pretty rugged. Zippers work well and don't have huge issues with catching the fabric and jamming. I expect this bag to take abuse in stride.

Overall, a good choice if you're looking for a spare to have around the house or a first bag for car camping on a budget. If you're looking to get a sleeping bag for backpacking, I would recommend trading up a bit in price for big improvements in weight and packability.

Have used it for car camping and so far so good. Keeps you warm and is comfortable. Doesn't pack super small in the sack.

It is really comfortable and soft, but a little bulky and heavy. I would not recommend it if you do backpacking.

I finally bought a sleeping bag! I absolutely love it and have only tried it once. The weather got down to about 40 degrees at night and I was completely content warmth wise. I am very impressed with the overall quality of the bag as well as the more specific things like the zipper and shape.

In terms of weight for a synthetic bag - I believe it is a great weight. Not too heavy so it is nice to attach to the bottom of your backpacking bag. You barely notice it is there. The stuff sack that is provided is of great quality and it is really easy to get the bag back in the stuff sack which is key in my mind.



Conclusion: solid bag from ALPS Mountaineering - first piece of equipment I have bought from them and I am completely 100% satisfied. Note: This also has a 0 degree option if you are looking to go camping in colder weather.

So far this bag is everything I've wanted it to be. It retains an amazing amount of heat. I'm not super tall 5'9" but i do have a wide stocky upper build. Yet with this bag I'm able to turn from side to side without getting all twisted up in it. In fact at around 70lbs. If I lay on my side even My service dog can fit in and we both stay quit warm on those nights were the temp just drops.

For now I'll gladly give this sleeping bag a 4 star till I get in some further testing this October. Cant wait! Thank you Backcountry. You guys/gals have become my go to for outdoor sports and gear. the only bad thing is this comes with pretty much a basic bag. Its NOT a stuff sack. NO STRAPS AT ALL.

Purchased this bag knowing full well that synthetic fill bags don't compress very small. Planned on using it with an external frame Kelty pack strapped to the outside. Purchased the Alps "cyclone" compression sack size M to go with it (btw, this is by far the best compression sack I've found, but that's for another review). Given the high loft and generous fit, I was surprised to actually be able to stuff it into the bag compartment of my internal frame pack. Works with mine, but can't guarantee it will fit in yours.



As I said, this bag has a more generous/spacious fit than most mummy bags. Finally a mummy that doesn't make me feel claustrophobic. Once it's had a chance to expand, the bag/loft is fairly thick. Haven't put the temp rating to the test. I've used it almost exclusively Spring, Summer, and Fall. I didn't freeze at 40 or sweat at 65. Did spend one night in it below freezing, but I was wearing a level 7 ECWCS primaloft suit so that doesn't really count.



As of now, I got about 30 nights in this bag and aside from some dirt, it looks brand new. So far it's wearing well. I do store it in a large tupperware so it has plenty of room to breath. Did get the zipper stuck once, but was able to get it undone. The hood and draft collar work pretty good. It zips from both the top and bottom. 3lbs 12oz isn't bad considering the size of this bag and that it's a synthetic fill. Have 20F down bag that is a lb lighter and compresses a good 30% more, but it also cost 5 times as much and takes forever to dry out.



This bag is very good quality for the price. Not for ultralight backpacking obviously, but good for most purposes. I like it so much that I bought the -20F version in XL wide for hunting season, but that one is big enough for 2 of me and weighs a lot more. Not something I would ever pack.
