Kelty Cosmic 20 Sleeping Bag

This 20 degree down bag by Kelty that has been recently updated to offer some new features and specs.

Things to consider when choosing a sleeping bag:

Sleeping bags are one of the most important pieces of gear taken into the backcountry. There are a number of things to take into consideration when selecting/evaluating a sleeping bag and I will address them all during my review of this bag:

  • Temperature Rating
  • Weight
  • Fill Type
  • Style
  • Compression Size
  • Cost
Temperature Rating: 20° / -7°C

A 20 degree rating means this is a 3-season sleeping bag (maybe 4-season depending on where you are using it) that should keep those using it comfortable down to temperatures of 20 degrees. I will make sure to test the bag out in conditions that are at or below this temp range.

Weight: 2 lbs 13 oz / 1.266 kg

I am testing out the “Regular” sized Cosmic 20. At 2 lbs 13 oz, I wouldn’t place this bag in the lightweight category, but it is a respectable weight (especially at it’s price point).

Fill Type: 600 fill DriDown™

Natural down fill is “treated with a molecular level polymer, creating a hydrophobic finish on individual down plumes. The result: DriDown™ stays dry longer, lofts better, and dries faster than untreated down.”

Ethical sourcing of of down is a big concern for many consumers. Kelty utilizes the services of in order to determine where the down in their bags is sourced. It just so happens that the down in my bag, was sourced from a facility in Anhui, China utilizing grey duck down.

Style: Mummy

Mummy style sleeping bags are made to be more narrow around the shoulders and hips, but this can sometimes cause the bag to be restrictive and even uncomfortable. I got in the bag and found it to be rather spacious for a mummy style bag, giving more space to fidget and move.

Compression Size: 8 x 14 in / 20 x 36 cm*

Compression size can be a big deal when it comes to sleeping bags. The smaller the bag can compress, the less space it takes up in the backpack. The bag comes with it’s own compression bag which has a compression size of 8 x 14 in / 20 x 36 cm. I plan on using a different compression sack that decreases the compression size of the sleeping bag to 8 x 10 in.

Cost: $159.95 MSRP

For the weight, down fill, and temperature rating, this price is going to be very hard to beat with other bags out on the market.

Initial Impressions:

With the combination of down fill, weight, compressibility, and temperature rating at a price-point of $159.95, this bag appears to be an incredible value at first  glance.

I plan on testing out the bag on a few backpacking trips over the next three months. Check back in about a month to see my next update on the Cosmic 20 sleeping bag.

Thanks to Kelty and 4AllOutdoors for the chance to review this bag.
