The Expedition-Cover Gore is a classic bivy bag – absolutely waterproof and breathable. But with one difference: With the zip-in-zip system you can zip your sleeping bag into the bivy bag. Getting in and out is just as comfortable as with a sleeping bag without a cover.
A bivy bag can be necessary if you do not find a site for a tent, are forced to sleep outdoors or just don’t want to carry a tent. That means a bivy bag can be essential for comfort and for survival! We use only best materials available on the market: GORE-TEX® Gas Permeable Technology is a unique three-layer laminate, absolutely waterproof and extremely breathable. Unlike the GORE-TEX® Membrane, that is used for clothing, GORE-TEX® Gas Permeable Technology is air-permeable As a result, our bivy bags can be closed completely, providing absolute weather protection along with great comfort.
