Tern

 

Tern
The Tern is perfect for the alpinist who requires the utmost efficiency for climbing, or the backcountry skier who is trying to minimize pack size. The techniques we use making sleeping bags for the world's most extreme conditions have helped us in building this highly refined mummy bag made to go almost anywhere. The Tern is a true winter bag, with an oversize collar, hood roll, head-to-toe differential cut and a side block baffle. Our unique compound draft tube functions like double draft tubes do, but nests tighter (using a convex and concave shape) to seal out drafts and reduce weight. Our quality is legendary and has received high marks on every review. Backpacker Magazine has this to say about the Tern. Check it out for yourself!
