Kelty meticulously designed the 20-Degree Light Year Down Sleeping Bag to give you maximum warmth with minimal weight for your summer backpacking trip. The differential cut gives you extra loft for heat retention, and the two-way locking zipper lends a myriad of venting options so you can regulate your temp.

  • The 600-fill down insulation compresses and rebounds well and features a high warmth-to-weight ratio
  • Slant baffle construction helps keep insulation in place
  • Top baffle collar prevents heat around your head from escaping
  • Sleeping bag security loops mean you won't wake up with your sleeping pad lying several feet away from you (or under a greedy camp mate)
  • Hang loops make it easy to store and air your bag
  • Zippered chest pocket gives you a secure place to keep valuables
  • Compression stuff sack and storage bag included

Great Bag!

  • Familiarity: I've put it through the wringer

This is a very comfortable bag that packs small and light. I have used it on a therm-a-rest pad and always have gotten a good nights sleep. Recommend this bag for 3-season use and possibly even 4 season with layering for warm sleepers like me. All around great bag!

Great 20 bag, warm, packs small, light

    Subject says it all. I waited about a year before writing this review and have probably about 2 weeks of nights in it now. I bought this after a couple miserable years with another 20 degree bag that lost its insulation and was over-rated from the get go. It was really a 30 or 40 degree bag claiming to be a 20 bag. This bag was a very pleasant surprise after this experience, a lot of value from Kelty, it has a lot of insulation and is warm. It hasn't let me down once in any fashion. there are a couple small feature items near the upper part (like an adjustable wind collar, this one isn't adjustable) but it's pretty damn good and I'm very happy with it. Extremely high quality and value. Including after washing.

    Almost 5 of 5

      This is an amazing bag, its very compressible (to about the size of a soccerball) and I experienced no problems with the provided compression sack. And the provided storage sack makes a great pillow when filled with a jacket and other misc. cloths. The only thing that I'd say is a bad is it isn't quite a 20 degree bag, at about 30 I had to throw on base layers. But the good definitely out-weights the bad as winter camping isn't my gig.

      The temperature a sleeping bag is rated for is the bare minimum temperature at which it will keep you alive, but you will be far from comfortable. The rule of thumb is to get a bag that is rated at least ten degrees lower than the lowest temperature in which you expect to use it. But the caveat, once you hit that 10 degree buffer zone you will definitely need to add more layers.

      Great Sleeping Bag

        First off I would like to say the sleep bag is great and compresses really small. The only problem I have was the compression bag. The first day I received it I tightened the straps twice and the stitching broke on two of the them. If you plan on getting this bag make sure you budget for a granite gear or other name brand compression bag.

        I really wish Kelty would have not included the compression bag and lowered the price a bit. I contacted them and they I can pay to have it shipped back and they would "evaluate it" and it was deemed faulty they would send me the same exact bag back. After shipping cost and waiting to get the bag back your better off buying a quality compression bag. I do understand that Backcountry has a great return policy but I got it for a good price and I would have to return the whole thing so I'm better off keeping it.

        After previously owning a Big Agnes bag I...

        After previously owning a Big Agnes bag I am addicted to their sleep system (the one where your sleeping pad is secured beneath the bag). Do Kelty's "security loops" really help hold, say, a Thermarest inflatable mattress in place?

        Damn, sounds like you could just wrap yourself in a Hefty bag and do just fine.

        I'm gonna go with either a Western Mountaineering Alpinlite bag to keep you at the 20 degree mark, or the Megalite if you can go up to a 35 degree rating. Arguably the finest bags in the world.

        For the tent- I would go with a MSR Carbon Reflex 2 or a Big Agnes Seedhouse SL2 for something a little less spendy. All excellent gear.

        Enjoy!
