Technical

Thinsulate

Thinsulate is a synthetic wadding specifically made for outdoor clothing. Its great lateral stability needs less stitch-thru than other waddings, giving excellent warmth/weight performance. Extremely warm and resilient.

Water-resistant Drishell outer fabric (weight: 54 gsm)

Ripstop nylon with an ultralight coating: achieves total windblock, along with high breathability and superior water resistance. Superbly efficient for a very light overall fabric weight.

Sizing

Reviews

"Last week I climbed the North Face of the Eiger ... only the 2nd time a British Guide has done this. We had two bivys on the face and one on the summit. Conditions were difficult and we wore crampons for the entire route. Both my self and my client used your Zeta 2 sleeping bags. They were just fantastic and completely idiot proof. "
