Product description

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 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
