Description of Sierra Designs Trade Wind 15°F Sleeping Bag Regular Outside gave the Trade Wind its "Gear of the Year" award in 2006 because it does it all—Drizone protects 800-fill goose down from moisture, while tuck stitching keeps seams away from water and potential abrasion. On the nastiest, coldest night you can imagine, jump on in and cinch down the ergonomic hood, seal 'er up, and sleep comfortably with an ergo foot box and cozy Pad Locks. The Trade Wind goes high alpine in the summer, ski touring in the winter, and laughs off the harshest weather you can find.
