Sierra Designs Trade Wind 15 Degree (2008) Sleeping Bag

Product Highlights

Updated for 2008! By coupling lightweight, compressible down insulation with an innovative waterproof, breathable shell, the Sierra Designs Trade Wind 15 Degree sleeping bag garnered Outside Magazine's Gear of the Year Award in 2006. Perfect for varied conditions, the Trade Wind 15 Degree bag is a versatile 3-season option.

The Trade Wind 15 Degree is insulated with 600-Fill goose down. Down not only has a soft, comfortable feel, it has the best warmth-to-weight ratio of any insulation available. The feathers and fibers are renowned for their efficiency in trapping body heat and are very easily compressed, taking up less space in your backpack. Fill power is a measurement of the loft or "fluffiness" of down insulation. Specifically, fill power is the cubic inches of space occupied by one ounce of down. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet. Sierra Designs has addressed this concern by using waterproof Drizone fabric for the exterior shell of the Trade Wind 15 Degree bag, ensuring that the fill stays dry and performs optimally.

The Trade Wind 15 Degree utilizes a baffle construction in which panels are created by stitching the inner liner and outer shell together to form horizontal tubes. The tubes increase the effective life expectancy of the Trade Wind 15 Degree by making certain that the down remains distributed evenly throughout the sleeping bag, insulating your entire body without risk of cold spots from a lack of fill.

Features abound on the Trade Wind 15 Degree. Built-in pad locks help to keep you from rolling off of your sleeping pad while you sleep. Sierra Designs' innovative snag-free zipper tracks protect the liner by creating a barrier which prevents stuck zippers. An integrated hood reduces heat loss. A fully-insulated draft tube sewn behind the zipper keeps cold air from reaching the inside of the sleeping bag.

The Sierra Designs Trade Wind 15 Degree sleeping bag is available in Regular (fits up to 6'0") and Long (fits up to 6'6") lengths. A stuff sack is included.
