Feathered Friends Snow Goose EX -40 Sleeping Bag

The Snow Goose is the world’s premier high altitude expedition sleeping bag. This model shares many design elements with the warmer Snowy Owl but delivers superb warmth at a lighter weight. We eliminated the second (inside) zipper and scaled back the hood and shoulder regions, but retained the efficient contoured shape that keeps full loft of the 900+ fill down around the head for maximum warmth.

EX: Winter & Expedition. Pertex® Shield® fabric. 15 denier with 40 denier rip-stop reinforcement. Water-resistant/ breathable.

Ideal for: High-Altitude Expeditions, Frigid Winter Camping, Polar Trips

A note on sleeping bag sizing:

When selecting a sleeping bag, the length and girth are the most important roles in warmth and comfort. If there is too much room at your feet, it is very difficult for your feet heat the excess air to a comfortable temperature. If your bag is too short, it is difficult to stretch out and sleep comfortably. Although gear storage is a factor in some cases when selecting length, it is advisable to select a bag closest to your actual length.

The most common issue when selecting the proper girth is efficiency versus comfort. The wider the girth, the more comfortable and roomy the bag but it is also less efficient. Consider selecting a bag that can allow a comfortable yet most efficient interior space. This way you can assure many comfortable nights of sleep so the following day your body can operate at its optimum ability.
