Warmth, compressibility. Definitely recommended. For any person planning a backpacking trip in early spring, late fall, hut ski trips, mountain climbing, camping, etc.


  • Warmth
  • Compressibility

I am an avid backpacker and needed a relatively lightweight, heavy-duty, cold weather sleeping bag. This one fit the bill perfectly.

I live in Colorado, and the nights get very cold. This bag keeps you warm all the way to your toes. There is not a lot of moisture buildup. There may be some if it is slightly humid/ raining but not much overall.

For a synthetic cold weather bag, it compresses well. Not quite as well as down, but it is worth the extra space. After unpacking it, it immediately fluffs right back up into a puffy, warm bag.

The coldest I have used it in is 0 degrees, and I was completely snug. I have had it for three going on four years now, and it still works perfectly.
