The soft and comforting Cotton Ascent Sleeping Bag Liner inhabits the ideal middle ground between silk and fleece.
Built from a cotton for added durability, the semi mummy-cut Cotton Ascent Sleeping Bag Liner weighs 340g and comes with its own stuff sack. Though not as warm as microfleece or as light as silk, its strength, longevity and cost-effectiveness make it a great investment for extra comfort and sleeping bag protection.
