Natural fill materials must be dry to enable them to loft properly. When wet, natural fill material sleeping bags offer very little warmth. To enable your bag to perform in a wider range of conditions, Epic by Nextec® fabrics are our choice.

Individual fibres of fabric are encapsulated with an ultra-thin polymer film. Then a durable, breathable barrier film is placed between the fibre bundles. The Nextec process is patent protected and the result is a quantum leap in fabric performance - unreal water protection, killer wind resistance and hyper breathability.

Epic by Nextec® fabric is completely unique. The inside-the-fabric process means that wash after wash, year after year, the fabric maintains breathability, thermal efficiency and remains truly water repellent, to keep your sleeping-bag warm and dry.
