Great bag at a great price!

I bought this bag for my trip to Mt. Rainier coming up later this year. They recommend a 0 -15 degree rated bag when summiting in September. I had the perfect opportunity to try it out during the recent "Polar Vortex" so I put up my tent out back in the snow on a -2 degree night with a 10 - 15... Read More

  • Comfortable
    Verified Buyer Reviewed by Melissa from Westchester on Wednesday, January 25, 2017
    I have yet to use it outdoors as of yet, however the material is very comfortable and I slept like a baby! I had trouble getting it back into the bag it comes with, but you get the hang of it after a couple uses. It's fairly easy to zip up. Overall, I am pleased. So far so good:)

    Great zero degree bag, packs small!
  • Lightweight Cozy Bag
    Verified Buyer Reviewed by theHayeser from Catskill Mountains, New York on Thursday, September 29, 2016
    I bought this bag for a backpacking trip to the Green Mountains in Vermont at the end of September. Although the temperature didn't drop below 35 at night, it was still a bit cold in the woods at night.

    I like to sleep on my side and bring my knees up a bit, and this bag allowed me to do that without any trouble. I expected some difficulty with that because it's a mummy bag. I had no trouble with the zipper, which in most bags gets caught in the material most times you zip it. And I like the Velcro that covers the zipper at the top to keep it secure.

    It also has a drawstring to pull the hood down over my head, which helped to keep me nice and warm at night.

    Overall, really happy with this bag. Great price for a zero bag that is lightweight, portable, and warm.
  • Nice and warm sleeping bag
    Reviewed by Mike from Minnesota on Sunday, June 5, 2016
    I purchased this in early spring to use for a scout camp out the last weekend in April. Both nights the temp dropped to 32-34 degrees. Stayed nice and toasty. Going to use it on a SD week long trip in July and 6 days in the BWCA in late August.
  • High Quality Sleeping Bag
    Verified Buyer Reviewed by Torgy from Minnesota on Wednesday, September 2, 2015
    I bought this tent for my wife in preparation for some late fall and early winter camping we plan to do along the Superior Hiking Trail and the BWCA. It's a very well made product and preliminary testing indicates it generates and maintains good warmth. It rolls up and fits into a neat cinch sack with several tie downs like most modern quality bags do. It's rated for 0 degrees, but it's barely noticeably larger than my 35-degree Marmot. Still, we wish it was a tad smaller so it could fit horizontally rather than vertically in my wife's Gregory Deva 60. Overall a great sleeping bag.

  • “I am a female does this really matter, so many bags are available in gender man. I like this one and it has better specs than the women's ones that seem too small. I'm 5.7”
    Asked by Lou from Grand canyon on 11/27/2016 1:04:42 PM
    • Women-specific bags are designed to fit a woman's contours. When compared with men's bags, they’re shorter in length (usually designed to fit someone up to 5'6" in height), narrower at the shoulders and wider at the hips. Often, there’s extra insulation in the upper body and/or footbox.

      Note: Smaller women may find that some youth bags can offer a comfortable fit. However, these bags may not offer all the performance features and equivalent temperature ratings of an adult bag.
