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

My problem: I camp in 30-40 degree weather at least one weekend/month through fall and spring. My mummy bag, while rated to 20 degrees is (a) not warm enough and (b) makes me super claustrophobic so I cant' get comfortable enough to sleep. This thing fixed both problems.

The Razor is larger than my mummy bag (a short women's bag), so I can zip all the way into the Razor without getting claustrophobic. (It even has a hood!) Then, I lay my unzipped mummy bag over me, comforter-style. I spent last weekend camping in the 30s at night, and this new set up was excellent!

I just might survive this season's Joshua Tree trips yet...

I still want to eventually upgrade to the Backcountry Bed, but until I can afford that price tag, the Razor has made cold-weather nights tolerable. Well, well, worth the price.

(Also - as others have said, this thing can be used as a warm-weather sleeping bag. As the morning warmed up, I pushed my unzipped mummy bag off me and was super comfortable in just the Razor. Unfortunately, I rarely get to experience the joy of sleeping outdoors when it isn't cold!)

Hi Leslie... I noticed you have been to Joshua Tree NP for several times.. I am planning to go there at Dec. Would the temp be around 30 F at that time?


Great warm weather bag

  • Familiarity:I've used it several times

I bought this specifically for summer backpacking. It packs fairly small and is warm enough for when a summer night turns chilly if you add socks or even a full base layer on cold nights. It's cool enough for those hot nights where you unzip it most of the way. I'm 5'10" 190 and it's a good size for me. I don't get cramped but I'm not swimming in it. It packs down fairly small and if you're careful you can actually pack it into itself using the "head" as a form of wrap for the rest of it. It doesn't pack to its smallest that way, but you can then compress it with other items. Sure, for a few hundred dollars or more you can get a down bag you have to keep dry that packs down smaller and weighs less, but part of the appeal is that this is inexpensive enough to have in addition to other options. I'd rather spend the extra money on a bag for cooler weather. I'm not sure how this really qualifies as a liner, but I guess if you have a slightly oversized regular bag you could use it that way. It's clearly designed to operate as a stand alone unit though.
I've only used mine four times, for a total of six nights sleep, but I'm quite happy with it and can't imagine finding something better for the price.

Does this liner have a "pillow pocket" of any sort to stuff in that annoying little runaway pillow of mine?

could I use this bag for summer camping where I need it to compress down to a small size ( canoe/hiking trips )

Hey elliot,

Thanks for your question.

This is not a sleeping bag. It is only a bag liner. If you would like to find a bag that can compress really small I suggest you hop on chat and get in touch with our gearheads (chat is available 24/7). You can also call us at 1-800-409-4502 (6am-10pm).

Grant I love you but, this customer should call us 1-800-409-4502. I bet on a warm summer night you could get away with this as a stand alone bag, I would still worry. Even nights in the desert get kinda cold, I am always psyched to have my 40 degree synthetic bag. If your going ultra light weight hiking then you are planning to suffer anyway, this might just be the ticket.

Grant and Bill I love you both and I don't disagree with either of you.

These liners are really only designed to add about 5-10 degrees onto a bag and I think for summer camping they CAN be great as a standalone but only in conditions where you would feel safe to sleep fully exposed (no bag or liner) and just want that extra comfort. Otherwise, why risk it? Get a decent 40 degree bag like Bill suggests and sleep with it unzipped if it starts to get too warm.

Hello Guys. Just wanted to let you know that the manufacturer does state the following on their site: "Great as accessory or standalone bag" and under the description tab: "As a standalone bag, it can be used in warmer temperatures when you only need a very lightweight bag." . So, yes, it can be used as a light standalone bag but the problem lies in the rating, which does not exist for this bag. Opinions I've read here and there are that this is a 50 to 60 degree bag. I just ordered one of these for my 20 degree bag since it will be the first time I will be ever cold-camp at the RMNP next weekend.

Does this bag pack down small enough to place in a pannier for bicycle touring?

Best Answer

This is just a liner, not a sleeping bag, so yes, it packs down quite small. About the size of a grapefruit (or smaller).

Actually, I just got this liner from SAC, and it is much larger than a grapefruit. It is about 8" tall x 6.5" wide in the stuff sack, straight out of the box (I can never get stuff to compress back to as small as it was out of the box, so I'm guessing this is as small as it gets.)

I tend to sweat against the nylon sleeping bag. Is the internal material fleece or other? And how is it for sleeping against / moisture wicking? Thanks...

The internal material is a thin, grey fleece. Another Scoutmaster bought one of these on sale and was demonstrating it at the last meeting. He is a big guy, 6' and close to 300#, probably 50 inch chest. He had room inside to zip the bag and move his arms.

Any tall folks try this out? good to 6'4"???

The length on the ALPS Mountaineering Razor Fleece Sleeping Bag/Liner is 80" so you should be in good shape being 6'4" and you can fit most long (6'6") bags in here.

Best Answer

I just got one and I am 6'6. Its a little snug at the feet but it fits pretty well.


Solid so far.

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

Used a few times after purchasing late fall and it has done the trick in my only bag (a 30 degree summer bag). Gonna wait and see how it does for winter camping and hammocking.

Have you used the liner this winter yet? I've also got a 30 degree bag and use a hammock.

Nope haven't gotten it out yet, but will update when I do.

Used the bag a few weekends ago along with my bag, pad, hammock and underquilt and man was I toasty! Temps dipped down to below 0F in the Uintas and I stayed warm in long underwear and a baselayer top!


Ranger rific!

  • Familiarity:I've used it several times

I just got mine the other day. And it great. If you know how to roll and pack gear you can get this sack super small. Its very warm and Im 5'9' 180lbs and I have plenty of room. When you have slept on roof tops in Iraq or in the snow and mud In Afghan with nothing more then a rain poncho and your wobbie. This thing is a 5 star hotel.


Bumps up the temp

    This is a pretty sweet liner.. not super compressable, but definiltey adds some warmth. Its super soft on the inside, and the outside moves nicely inside of beefier bag. Great little bag to keep you out later in the season!


    I used this standalone.

    • Familiarity:I've put it through the wringer

    I used this standalone for a 30-day bike tour, sleeping outside every night. I was cold once, when it got to 40� at the top of Mt. Hurricane in the White Mountains in August. I wasn't that cold- I still slept. It performed admirably in all other temperatures including 45�.

    Does this come in a small stuff sack/com...

    Does this come in a small stuff sack/compression sack? Also, what are the dimensions when packed?

    I am not sure what the packed dimensions are, but it does come with a stuff sack.


    Comfortable But a Bit Bulky

    • Familiarity:I've used it several times

    I really like this liner. I bought it to add 10 degrees to my bag. I like the comfort and warmth this provides. The only reason that I give it 4 stars is because of the size. But I think it you are looking for a liner to add warmth you are going to have to deal with some bulk. There is no way some of those paper-thin liners add 10 degrees to a bag.

    Although I haven't used it this way yet, I think this will be a good summer bag as well. It would work well for any nights that don't drop to far below 65 degrees.

    Overall it is a good product for the money.


    good but not great

      a very warm and fuzzy liner. the only problems with it are that its a bit on the bulky side and that its very narrow. Its unlikely most users will be able to zip it all the way up


      Minimal... Just right.

        This bag is very light and packs down very small. I generally sleep pretty warm so I got this for camping in the dead of summer as well as to use as a liner for my other bags for winter camping and for travel. I think this thing is going to get a lot of use. Very basic. No bells and whistles. Full length left had zip. Mummy style hood. Velcro zipper stay. This is a good pickup.
