I love this bag.


  • Warm
  • Comfortable

Back story: As a scout in the '70s, late '70s, we camped year round and down versus synthetic was always a hot topic. At some point my parents got me a synthetic mummy bag that wasn't as warm in February as some of the huge down bags. In 1979 I went to Philmont and in ten days it rained six, wettest year on record. Wet night after wet night I was ever so glad to have a bag that was warm when wet.

When my kids were young they each got Disney sleeping bags that were fun to snuggle in or use on sleepovers.  One night we were at Eastern Mountain Sports and they were closing out this bag, or this color. I couldn't resist the price and it looked and had the same synthetic material as my Philmont bag so I got one for each of the kids.

As it turned the kids never used them together. Either my wife or I went camping and used the other bag. Two Novembers a group of dads in town would book the whole Zealand hut in the White Mountains and I remember them talking about all of the strategies for staying warm. At first I though I just had warm years but I figured out that this bag was really comfortable and warm, especially at high twenty, low thirty temperatures in the hut.

My only reservation is that the bag is big when in the stuff sack.

With the Cosmic, Kelty delivers a terrific three-season bag. It has a great feminine look and a terrific sub-$100 price tag.


  • Great styling
  • Warm
  • Sub-$100


  • Heavy

Kelty positions the women’s Cosmic 20 as a bag that spans “cool spring nights into a brisk fall” and does it all for a bargain price (sub $100).

We were struck by its decidedly feminine look — thanks to the light blue and brown polka dot color scheme and embroidered flower accents. But this bag’s beauty was more than skin deep. We chose the Girl Scout Camporee over Memorial Day weekend for our test. In the coastal mountains it felt more like a winter in Siberia than Summer in Santa Cruz, but with this sleeping bag we were cozy and warm through the frigid night.

Great bag for the price ... took it out for an overnight late winter and slept nice and cozy at 28*F in my tent with my DIY footprint bubble foil insulation.

Kelty Cosmic 20F Synthetic BagThe Kelty Cosmic 20F Synthetic Bag is a snooze solution for the budget-minded traveller. The zipper on this sleeping bag ensures that the zip won't slide up and down while you sleep, even if you kick around. The differential cut maximizes warmth inside the sleeping bag and gives it extra loftiness. The drawcords allow you to make sure a custom-fit for extra warmth. For especially cold nights, the internal liner loops can be used to attach a liner, as an extra layer. The ground-level side seams prevent heat from escaping the bag. The hang loops are an easy storage solution during the day and they offer you more room to walk around your tent. The insulated hood baffle keeps your head warm and acts as a pillow too. If you love your warmth even in the cold outdoors, get yourself the Kelty Cosmic 20F Synthetic Bag.
