This bag is hotter than ever. Seriously. The Cosmic down 20°F sleeping bag has been restyled for 2016 and now features the exceptional warmth of 600-fill hydrophobic DriDown™ for higher performance. That means more moisture defense and quicker drying in the cold and wet. Versatile enough to use in 3 seasons, with great features like a thermal comfort hood and top draft collar, it’s a no-brainer for backpackers who love to be outside in rain, snow or shine.

    1. Economical light weight bag

      Just finished 27 miles on the PCT using an Ultimate Direction 30L pack and the Cosmic 20 packed into a compression bag. While still the largest consumer of space in my pack, the sleeping bag is still light and warm. I use a hammock to sleep in and many bags struggle to not lose warm without extra padding, this bag did just fine. Note that it was warm 91 deg high 55 low. Any temps below 50 I will likely use a sleeping pad for insulation. on Aug 12th 2017

    2. So far so good

      I took this on a backpack trip to a lake at 8300ft in Idaho 2 weekends ago and it performed great. I actually got a little too warm at one point. I think the temperature got down to about 30 degrees outside at the coldest. I think it would keep me warm to 20 degrees. Would be nice to have a stuff sack that compressed it a little better and didn't feel so cheap as a previous reviewer noted but all in all pleased with this bag so far. It replaced a lafuma warm n lite down sleeping bag that was rated to 30 degrees. I ordered the regular and at 6' tall was worried I would be maxing it out but it was perfect fit and I'm now glad I didn't get the tall version. on Jul 3rd 2017

    3. Good bag - stuff sack included is useless

      Bag compacts down well and is good for backpacking. I had it in 40 degree weather this weekend, don't think it would keep you comfortable in 20 degrees. The stuff sack is really thin and cheap, the pull cord doesn't hold at all, pretty much useless. on Jun 25th 2017

    4. Great bag, with one major flaw

      Warm, affordable, dry, durable (albeit the zipper) and easy to care for, however the zipper is a major issue. Had this bag for 2 years used it hard for 6 months on a Type 1 Hotshot crew, fabric held up great, doesn't wet out, and warm right down to the EN value. Just wish the zipper was of the same quality as the bag. Snags very easily and now I'm laying in my tent on a cold end of March night on the Lassen in a bag that doesn't zip cause the zipper fell off. She's had a short but hard life I suppose. I didn't pay full price for the bag and even if I had it still is a good deal, just mind your zipper. on Mar 28th 2017

    5. Fantastic Sleeping Bag

      I just purchased this bag - I am 5'3" and it fits perfectly with room to spare! My husband and I backpacked to San Gorgonio Moutain and set up camp at High Creek Camp. The temperature was about 49-51 degrees and the sleeping bag kept me Toasty! It was comfortable and surpassed my expectations. Highly recommend. on Aug 1st 2016

    6. Good Bag but Weight Spec Wrong

      For the price, there might not be a better bag.

      I purchased the 2016 Cosmic 20 Long Model.
      "Size Long:
      Fits to: 6 ft 6 in / 198 cm
      Fill weight: 25 oz / .709 kg
      Total weight: 2 lbs 13 oz / 1.276 kg"

      The specs are not accurate. Total weight on the packaging and attached bag tag reads 3.1lbs. I placed the bag, sans stuff sack on a scale and 3.1 was correct.

      If you do purchase this bag. please keep this discrepancy in mind. I don't know if the other sizes are accurate. Someone else will have to check the weights of the Short and Regular.

    7. Great sleeping bag

      The cosmic 20 sleeping bag is a very good price and offers great warmth. I would recommend to anyone needing a new sleeping bag. The lifetime warranty is a huge plus, too. on Jun 29th 2016

    8. Great value, good wt, bit bulky.

      For the cost, it's hard to beat. Roomy and if the rating is accurate, warm for its weight. Water repellant down at this price?! Pretty great. It is somewhat bulky and the stuff sack makes it nearly as small as possible. Not quite as light as my 800 fill bag and a bit bulkier, but at $200 cheaper, not unexpected. on Jun 15th 2016

    9. Perfect sleeping bag

      I recently bought this bag and used it every night for 5 weeks ranging from slightly below freezing to warm/cool temps. The nights it was freezing, I had a light base layer on and was really warm. The warmer nights, I just unzipped it and used it as a blanket. After using it for 5 weeks straight, I was expecting some wear and tear, but it held up perfectly: no tears, loose threading, zipper malfunctions, loose down, nothing at all. Also, somehow there is no smell: I went into this bag stinky and smoky and it did not keep my stench (I think I took 5 showers the whole trip). Lastly, To save on space I opted for the Ketly compression sack. The medium size works well and doesn't feel like it will damage the the loft when compressed. The bag fits into the small compression sack, but it was a little too compressed for my personal comfort with a down product.

      I am a 5'10 dude and the regular size was perfect.

    10. A great 3 season bag for New England

      I bought two of these Cosmic 20 bags (2015 model) for my son and I. We used them on the rim of the Grand Canyon at 20 deg F the first night with a self inflating mattress and a microfiber liner and we both slept comfortably. They stuff down reasonably small and the materials are good while the weight is not bad. I couldn't find anything at the price to compete with the Cosmic 20.

      And for 2016 it looks like Kelty has moved to ripstop nylon and 600 fill down to save a few ounces making a good bag better. My 2015 bags are dark blue taffeta (non ripstop) and 550 fill down.

      From my research, you'd have to spend 2 - 3 times the price to get a significantly lighter bag with the same rating. Nah, I went for the value this bag represents.
