Kelty sleeping bag

Just returned from camping in the Smoky Mountains during the hurricane, 9/24-10/1. Heavy rains, very windy but not very cold. I have a light weight Kelty sleeping bag but I took the new one. It was everything I expected. Light weight, comfortable and warm. Slept in my Kelty tent and stayed completely dry and warm, a little damp due to the heavy rains though. A good bag, I recommend all my Kelty purchases. Quality products!!

Stay Warm and Comfortable

This sleeping bag is awesome. The material is so soft, it's lightweight, and really made camping so much better. Literally can't get over how soft it was. Next to my girlfriend's sleeping bag (Not kelty) this thing was far superior in comfort and compactness. The only thing is I wish I went for a long size at 6'1. I am right at the cusp of this bags length and wouldn't have minded a little bit more room to get cozy. Still super happy with the product!

The pocket is on the chest

Garret, the pocket is on the inner lining that would rest on your chest if you are zipped in and laying on your back . Kelty bags are all we use. Great product.

Per usual, very happy with Kelty

Let's face it- when is backpacking ever actually easy? While it's can't take the pain out of your elevation gain, Kelty CAN put you on the trail with the new Cosmic Synthetic 40 Sleeping Bag. It's a fully equipped mummy bag that's light on weight and your wallet.

The Cosmic synthetic is a three-season superstar built with Kelty's new CirroLoft synthetic insulation for lightweight, compressible warmth. Soft-as-silk nylon taffeta fabric means you'll be thinking less about weary hiker feet and daydreaming about more QT in the outdoors.
