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...

Can you zip two bags together?

Hey Jan,

this sleeping bag won't be able to be zipped together with another of the same bag as it only has one side zipper. Let me help you find a bag that works by emailing me at bsneyd@backcountry.com

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!

      Toasty toasty

      • Familiarity: I've used it several times

      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!!

          Black Canyon Of The Gunnison

          • Familiarity: I've used it several times

          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.

          Perfect for Car Camping

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

          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.
