Sea to Summit
XT I 19° Sleeping Bag
Out of Stock Product Number: 25326
The Sea to Summit XT I 19 degree sleeping bag is Sea to Summit's most versatile down sleeping bag, and one of the Traverse Series bags designed for a variety of activities. This sleeping bag is EN-rated to a lower-limit temperature of 19 degrees F and a comfort temperature of 30 degrees F.
The Traverse Series down sleeping bags offer comfort in a wide range of temperatures. Sea to Summit uses the highest-quality European goose down available, rated at 850+ loft and backed up by a certification document included with each sleeping bag. The patent-pending 3D NanoShell™ technology repels external moisture and keeps condensation away from the down insulation. Innovations like the 3D Sidewall and Reverse Differential Cut keep that insulation in place, and close to your body, for maximum thermal efficiency. Temperature ratings are the result of honest, third-party EN testing performed on each sleeping bag.
Designed with a relaxed mummy fit and separate foot zip, the XT I can be unzipped into a full duvet for sleeping in huts or closed tight for winter camping in sub-freezing conditions. Side block baffles maintain a 60:40 fill ratio, with more insulation atop the bag where you need it most. An oversized neck collar, hood seal and zipper draft tube minimize heat loss. The soft-touch lining fabric is highly breathable for comfort, and a stiff anti-snag material ensures smooth zipper operation. An easily-accessible security pocket inside the bag is ideal for stowing electronics in extreme cold.
The Traverse Series is Sea to Summit’s choice for trekking the Annapurna circuit in the Himalayas, ski touring hut-to-hut in the Alps and walking the Western Arthurs in Tasmania. These down sleeping bags are so revolutionary we can’t fit all of the information here, so check out this series of articles on our blog!
