Mediocre Sleeping Bag

  • Familiarity: I've put it through the wringer

I was camping early in April. Thought this bag would suffice. Alhtough, over the course of 4 nights, it fell below 32 one night but above 20 (my water bottle froze) and I was freezing cold. Had to put a jacket on and jeans over pajamas. Don't think this bag is good for 20F. It's comfortable enough for the 35+ Range.

For the price, its not bad. Quality and make is alright.

Hot Pocket

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

I'm 6' 3", 215ish. The long bag fit well with a little room to spare, very comfy. With temps in the 30s, this bag was HOT. Did not sleep well at all. Should wait for colder weather to use this bag.

Great bag for the cost.

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

My overall impression of the Aleutian 3S is pretty good. The bag was comfortable to sleep in and roomy. I purchased the bag for backpacking and slept great in it. I did however, return the bag because despite being comfortable, warm and reasonably priced, the bag took up more space in my backpack than I was willing to accept. If you have a pack that has a compartment for a sleeping bag it probably wont fit without a compression sack. With that in mind, a down bag may work better. Other than that the bag is awesome.

Warmth-At An Affordable Price

    I got this bag about a month ago and have used it once in 30-degree weather. Combined with a sleeping pad it kept me warm throughout the night. This is my first mummy bag and I have to say they do take a little getting used to. But the Aleutian 3S is a good transition into the mummy bag camp.

    Comfortable, warm, and affordable-the trifecta I need for a good camping trip.

    Warmer Than You Think

      This was my first sleeping bag. I still use it to this day. On multiple occasions I've used it snow camping. It's even taken me through 0 degree nights in a snow shelter. All I do is throw a fleece liner in it and I'm just toasty. I will say I'm a very hot blooded person.

      I use a Sea to Summit water proof compression bag and it compresses unbelievably well and then expands right back to full size.

      Bottom line I'd buy again if I ever need to.

      I used the Sea To Summit eVent Compression Dry Sack. Backpacker magazine usually knows what they're talking about and they gave that sack an Editors Choice Award! It's amazing, it's taken spills off my kayak, been buried by snow and not a drop of moisture on it's contents. WORTH THE BUY!

      Great Bag, Kinda Bulky

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

      I bought this bag to have as my main cold weather bag. Out of the box I could tell that it would be warm, and it was. I took it camping in temps in the low 30's. With my tent and sleeping pad I stayed warm all night long!

      The only down side to this bag that I have observed is the bulkiness. It does come with its own stuff sack, but even in the sack its quite large. I just bought a 20L compression sack for it and managed to get it down to a manageable size.

      All in all, great synthetic bag for its price. I look forward to using it again soon. Hope this helped.

      I am right at 6' and have felt a little squished in some regular sleeping bags that supposedly fit to 6'. How does this one compare? Would I need the long size?

      This or the NF Dolomite 20? Mostly backpacking and camping, but it gets chilly up north here. Never had a mummy bag before, not sure how I'd feel about the feet being closed in. Any advice?

      Where are the specs for the L and XL. At 6'5" is a long going to cut it?

      Best Answer

      Their description of a long says it accommodates up to 6'6". Being that close to the max, I'd recommend finding a place you can test fit one before buying. Although BC's return policy is awesome, having to return it would still be a tad inconvenient, and downright maddening if you're approaching go time for an outing.
