    1. For years to come

      I've owned this sleeping bag for the past 3 years, got it as a birthday present. I like to do winter camping up here in Michigan, where in the past years the winters have been drastically different; ranging from 20s all season to sometimes in the consistent negatives all season. The coldest I've slept in was a ridiculous overnight we that consisted of -28 degrees Fahrenheit (my friend said it got to -32, but I didn't see the proof). This bag has kept me warm in times of need. And to this day with handle and care, the bag still holds good loft and provides good insulation. This is a great investment for your money, and has a little more range in my mind for all season camping. This isn't the best winter bag on the market by far, but it manages to not go down without a fight. on Oct 6th 2016

    2. Need more specifications

      I am looking for a low temp down sleeping bag but I need more information than you list.
      What are the internal shoulder, hip and foot circumferance of this bag?

    3. Great bag for the Price!

      This is a great, warm, comfortable bag. I originally bought one for my daughter and liked it so much I had to have one for myself! Its a little packed down when you first take it out of the compression sack (from the store), but quickly expands. Its very warm. Very nice bag for the price point! on May 17th 2016

    4. Worth it.

      I have the ignite 0 degree (an older model, I assume) and it has the dridown. It is rated to 0 degrees and comfort rated to seven, but I used it once when it was -12 out and I stayed perfectly warm. Great quality, nothing has broken in over two years since I got it and if you want a good sleeping bag, don't get anything other than this. It is so worth the price and you will not regret it on May 14th 2016

    5. Warm Bag Great Price

      I got one of these recently to replace a cold weather marmot bag I had. At first I was hesitant because of the lower price-point, but I used it many times now and am quite confident in its comfort and warmth. This dri-down stuff is no joke! Great value and great bag!! If only Kelty made apparel. on Mar 31st 2016
