The Cosmic Synthetic range provide great value for such warm sleeping bags. A generous amount of insulation, full set of features and impressively low cost.
Kelty says:
Let’s face it- when is backpacking ever actually easy? While we can’t take the pain out of your elevation gain, we 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 our 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.
Our Verdict
Kelty's Cosmic 40 Synthetic Sleeping Bag uses a generous 680g of CirroLoft synthetic insulation to deliver a warm bag that has a -3°C Comfort Limit. Although the synthetic Cosmic range are not the lightest bags you certainly get extraordinary value for money. It has all the features you'd expect from a top of the range bag with a draft tube down the anti-snag zipper, shoulder baffles and a good hood.
For the set of features and level of warmth at this price there are some other costs and these come in the form of a high weight and rather large pack size. For this amount of money you would expect some trade offs but when you consider just how warm and comfortable the bag is at this price it's hard to complain about the size and weight. It is an ideal piece of kit for car camping in particularly cold damp conditions.
