Our 0-degree mummy sleeping bag is filled with the durable, warm and water-repellant DownTek.
This down is specially treated with an advanced nano technology that absorbs one-third the moisture and dries two-thirds faster than untreated down, making this sleeping bag a great choice for backcountry trips in damp climates.
Revolutionary DownTek treated down stays dry
long and dries out faster, making a great insulator
even better. Watch the Video
