Beat the cold and the system.

It gets cold at night. Don't be caught underestimating this basic principle the next time you go camping; bring the warm bag. The Alps Mountaineering Crescent Lake 0 Degree Sleeping Bag can hang with the big boys in just about every area except for price. Techloft+ insulation is lightweight, extremely packable, and unlike goose down, retains over 70% of its insulating capabilities when wet.

Unanswered Question

are there zippers on both sides?



    it's a little bit BIG but the comfort rating is awesome. the price is so good for an element that will be helpful a lot of times

    hey, is this bag rated 0 degrees Farenheit?

    Best Answer

    Yep, temperature rating is in Fahrenheit. Keep in mind that temperature ratings are pretty subjective, depending on the person, tent, humidity, clothing, etc.

    Hey, there are zippers on the right side at head level, feet level and on the inside.

    The sleeping bag is rather bulky. However it is very comfortable. I'm 5' 11 and a half inches 175lbs and I fit in the bag with plenty of room to roll over from sleeping on my back to my stomach or even bring my legs up and sleep in a little ball. Its more of a camping bag than a backpacking bag in my opinion. Overall wonderful bag. I look forward to using it to sleep in comfort this winter.


    Bulky and HOT

    I love this sleeping bag, its super toasty and cozy, and so plush you dont need any cushion except grass. Honestly it would be my bag of choice except for how massive it is. Even with the Cyclone stuff sack this bad boy takes up too much room. Perfect for car camping or if you only have a mile or two to lug things in. I hiked about 7 miles with it and damn near threw it off the mountain (who am I kidding it was 30 degrees). Ive slept in this bag in 17 degree weather and was perfectly warm, I even had to take my wool socks off.


    Bag is good quality and warm, but bulky

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

    This is a good, warm bag for the price. I bought it as a gift for a friend I went backpacking with . The bag was warm and comfortable, but we did notice it was bulky size wise on the trip.

    Anyone know the dimensions for the Long vs Reg vs Wide?

    For stuff sack dimensions, click on the link under Specs. I imagine with enough work, you can stuff it into whichever compression bag you have/want to buy.


    Great bag just a little bulky

    • Familiarity:I've used it several times

    I've used this bag twice now in January. One night temperatures dropped to 33 and the other was 37. Both times I stayed extremely warm. I have a slumberjack which is rated for 20 but it never kept me this warm. The only drawback of this bag is the size. It is on the bulky side but for the price, you won't go wrong.


    Yes it's big, but it's so warm!

    • Familiarity:I've used it several times

    This bag may be rather colossal but it is soooo comfortable. I run really really cold but in this bag I am nice and toasty. The size and weight are definitely worth it to me, but may not be worth it to you.


    warm and bulky

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

    I got this bag because it was a good price but it is bulky! I was warmer than my friends who had more compact bags which was nice but the bag took up most of my pack. It was so warm and snug! it was about 30 or lower and damp rainy nights and I slept great.

    What is the weight of the bag?

    Great Bag, and Price!

      I've been using this sleeping bag for a couple of months now sleeping in a hammock and it has fit the bill wonderfully. The footbox is a little smaller than i anticipated but it's not a big deal. Its a great bag for a rainy weekend in the woods. I've slept in it down to 45 degrees partially zipped, but i believe even 60 would be do-able. I have no doubt that it will keep me warm down to Zero degrees. The zipper catches the inside if you dont hold it out of the way when you zip it up, but other than that i love it!

      I'm going on a horse pack trip the end of...

      I'm going on a horse pack trip the end of June in Montana. The guide recommends a 0 degree bag. I'm thinking synthetic to save money. Is this or the Kelty a better choice?

      Best Answer

      I have this bag. I'm 5'9" and flux between 175/180lbs. But this bag is prefect. Plenty of room and super warm. If I lay on my side even my dog. A 60lb american pitbull can curl up and fit in lol. down side is even with a compression sack is big. need bigger ruck/backpack thats all I guess.

      The regular size is too short for me or my son - both around 6'. I'm heavier (220lb) and feel claustrophobic. My son is 180 and likes the width. We are giving the regular to my daughter and buying two larger sized bags. Also, the zipper is tempermental immediately and may be a problem.

      Does this bag have a full length zipper?

      Best Answer

      Hey Kyle,

      This bag appears to have a full length right side zipper. See the photo I uploaded from the manufacturer product page. Hope that helps out.

      yes this bag has a full length zipper. And a velcro safety flap.


      so nice

        this bag is a little bulky but once you are in it you do not want to get out. Great bag for the price if you dont mind how big it is. I was also fine with out a sleeping pad because it so soft.

        What're the packed dimensions?

        Jon, here are the dimensions...

        Crescent Lake 0 Regular - 11" Diameter x 18" Length

        Crescent Lake 0 Long - 12" Diameter x 18" Length

        Hope that helps.

        With the Alps "cyclone" compression sack size L, I get my 0F Alps Crescent Lake down to about 9x16, but my bag is an XL wide... which is huge... so I'm sure the regular size would compress smaller.
