Are any of our Mummy/Ultralight Backpacking sleeping bags lined with cotton?Updated 2 years ago
No, none of our Mummy or Ultralight sleeping bags are lined with cotton. Cotton is a bad idea in colder climates. It doesn't wick the moisture away from your skin. It holds it against your skin and can cause hypothermia. Synthetics and wool (or a blend of the two) are preferable because they will draw the moisture away from your skin and help keep you warm and dry.
