Product Description
Remember the trapezoid from 10th-grade geometry? Turns out, this funky ol’ shape is ideal for helping sleeping bag baffles retain heat. The trapezoidal baffle construction improves on our best-selling Cosmic sleeping bag—and it’s just one of the reasons Cosmic is still our favorite three-season superstar. We also love the natural-fit foot box for happier feet, and a PFC-free water-repellent coating for a healthier environment.

Warmth you can count on:
550 fill power down: Lofty and toasty, this bag kept me snug as a bug in a rug even on chilly fall nights.
Trapezoidal baffles: These clever pockets keep the down evenly distributed, preventing cold spots and maximizing warmth.
Comfort that lulls you to sleep:
Spacious interior: I never felt constricted, even tossing and turning like a human pretzel.
Soft lining: The fabric is gentle against your skin, making it a pleasure to drift off to sleep.
Natural-fit footbox: No more cramped toes! This roomy design lets you wiggle your feet freely for ultimate comfort.
Lightweight and packable:
Compresses down small: Easily stashed in my pack, leaving plenty of room for other gear.
Durable ripstop nylon shell: Tough enough to handle the wilderness without weighing you down.
A few things to consider:
True to its 20° rating: While I was comfy down to the mid-40s, it might not be warm enough for true winter camping.
No bells and whistles: This is a basic bag, so if you need features like a draft collar or integrated pillow, you might want to look elsewhere.
Overall, the Kelty Cosmic 20° is a fantastic value for the price. It's warm, comfortable, and packs down small, making it a great choice for three-season adventurers. If you're on a budget or just starting out, this bag is a sure winner.
Happy camping!
I hope this short review helps you decide if the Kelty Cosmic 20° is the right sleeping bag for you. Sweet dreams!
That said, I haven't had a chance to use it yet.
However, upon inspection, it is lightweight, the regular being merely 40.6 ounces! It packs really small.
I've been using the black bag from the USGI issue sleeping system. This bag feels very similar to that one, and similar design. However, that bag weighs 60.8 ounces, and does not pack down very small. I am very impressed with how this kelty bag can compress down to. Just laying in it testing, you can feel how much warmer it is than the black bag as well.
My suggestion is if you are over 5'8", get the long version. Under that height get the regular. And the short for children.
It was easy to fit into the stuff sack and could get down smaller with compression. I do wish it would have come with a storage bag as well. The bag is much lighter and stuffs down much smaller than any of the synthetic bags I've bought in the past. Now that I've got a taste of the good life, I'm not sure if I'll ever be able to go back.
