Why We Like The Crescent Lake Sleeping Bag

A favorite of ours for its comfortable, straightforward design, the Alps Mountaineering Crescent Lake Sleeping Bag is warm enough for when we wake up to a ring of frost around the lake we've camped next to. Its Tech Loft+ insulation maintains warmth in humid climates, or if rain happens to dampen the inside of your tent. Plus, the Crescent Lake comes in a large stuff sack suitable for most car camping trips.

  • Sleeping bag best-suited for cold car camping trips
  • Tech Loft+ insulation has a 20F temperature rating
  • Full-length zipper with hook-and-loop strap at hood for coverage
  • Insulated baffles at chest and zipper offer draft protection
  • Large stuff sack included for easy travel and storage

Not backpacker friendly

  • Familiarity: I returned this product before using it

This bag is huge! Def not one you'll want to do multi-night trips with, it will take up your entire pack.

Good sleeping bag for the price.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I've only used it once for camping, and it did what I needed. Simple bag for simple camping, not for backpacking or extreme weather imo. good bag for the price

Not bad for the price

  • Familiarity: I've used it several times

Picked up for my son for short overnights. He had no complaints the couple times he has used it. I tried it and it's too small for me. In the bag's defense, I'm 6'2 and the bag was a size regular. So if you're my size, go large. Also, it says 20° rating, but I think that's a stretch. It is a good and cheap bag for short overnights in mild weather.

Great Bag for Price!

  • Familiarity: I've used it several times
  • Fit: True to size

This is a really nice syn mix bag for the price. You're not going to base camp at Everest, this bag will likely do you fine. We use this as a "family camping" bag.

Strange fit

  • Familiarity: I've used it several times

It's nice n bulky and warm. I like the color, and it was affordable.
As for the fit, I'm 6ft slim built, and I find that is very roomy, the neck collar however is positioned too low, so that it's not really effective, it's quite useless in keeping cold air out. The face draw cord is the only thing that helps.
Maybe a 5ft 8 person might like this better.

I've sold my expedition grade 0F sleeping bag... to take things more casually in the 20F range. I'll be looking for a more suitable replacement, when opportunity presents itself.

Cushy, but not very warm

  • Familiarity: I've used it several times

I've used this bag 5 times since I bought it this spring.
This sleeping bag is plush, and thick. I am an overweight side sleeper, and it doesn't bother my hip to sleep in this, on a thin pad. That being said, I did not use a good pad on a recent camping trip in the UP of Michgan, in late August. We were sleeping on sandy ground and thought I'd be fine. I WAS FREEZING, and the temp was only in the 40's. I had socks, sweats, a tank, long sleeve, and a fleece, with a hat. AND I had a microfiber bag liner. I consider myself a warm sleeper too, so I was surprised by how cold I was.

Zipper gets stuck a lot too. In the storage bag, this thing is huge. I have been putting this bag inside a 35L stuff sack to smoosh this thing down.

For the money, this bag is fine for a car camping trip , with a good sleeping surface.

Serves its purpose at a good price!

  • Familiarity: I've used it once or twice and have initial impressions

It’s a sleeping bag that has what you want for the weekend camping and is comfortable! Cool color way!

First Mummy Bag, Pretty Nice

  • Familiarity: I've used it once or twice and have initial impressions

This was my first 'serious' sleeping bag, I got it for an international trip I was taking where the weather was likely to get cold at night.
It's very long, at 5'4" I resorted to shoving all my clothes down into the foot to try and keep warmer, but as a side sleeper, there was room to move a bit. The fabric was super slippery, and in 50 degree nights, I woke up a few times the last few nights bc I was Just So Cold, and will be looking into a flannel/fleece liner. The ground I set my tent on was also sloped just a bit, so I ended up sliding down to the foot of my sleeping pad every night.
The zipper had a bad habit of catching on the fabric, and the velcro near the neck kept trying to eat my hair (which I don't fully hold against it), but I suppose it's a case of 'you get what you pay for', and overall it seems to be a pretty decent sleeping bag, if only for warmer weather.

Great Price

  • Familiarity: I've used it once or twice and have initial impressions

My wife and I were both looking for new bags that could handle the cooler nights when camping but that didn't break the piggy bank. After searching around, we landed on this sleeping bag and while we haven't used in cold temps we are very pleased with the quality for the price! Stoked to get out and use the bag ALOT

perfect for summer

  • Familiarity: I've used it several times

I liked my 0° version so much I bought this one too, for summer camping. Super comfy but the zipper gets stuck on the liner though.

Great Bag

  • Familiarity: I gave it as a gift but have feedback to share

Awesome bag for the price.

Great bag for the buck!

  • Familiarity: I've used it several times

We bought a pair of these for our older two boys (12 and 14) for scout camping. For them, the bags worked great. They stayed warm while camping near the lake at a moderately chilly ~45 degrees, and didn't complain of the zipper problems in other reviews. As a starter bag for scouts, especially for the cost, you can't go wrong.

Good for a budget, not for temps

  • Familiarity: I've put it through the wringer

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.

Overly toasty...

  • Familiarity: I've put it through the wringer

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.

Overly toasty...

Budget Bag of Awesome!

  • Familiarity: I've used it once or twice and have initial impressions

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.

Great value

  • Familiarity: I've used it once or twice and have initial impressions

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

stylist sleep sack

    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.

    Pretty good

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

      Best Budget Bag!

      • Familiarity: I've put it through the wringer

      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!

      Hey, I was wondering what size compression sack this would fit in? I was looking at the ALPS Mountaineering ones with 4 straps, but didn't know what size would be appropriate. Any guidance would be appreciated!
