Manufacturer: Patizon Product code: PAT126
A membrane bivy bag with a sophisticated closure system and an ultralight membrane laminate CRAFTEVO® from Japan.
The enlarged mummy shape provides enough space for a standard-sized inflatable sleeping pad, a warm sleeping bag and some additional equipment. The curved waterproof zipper with two sliders positioned together provides enough room to insert both the sleeping bag and sleeping pad, while also allowing you to position the breathing opening exactly where you need it. Properly oriented downward-facing storm flaps help prevent water from entering even when the breathing opening is partially open.
Excellent fabric breathability (RET below 4 / MVTR above 40,000) helps reduce moisture condensation inside the bivy bag. A waterproof rating of at least 10,000 mm hydrostatic head provides reliable protection against rain and snow. All seams are fully taped.
For sitting bivouacs, the bivy bag features a shaped hood with a laminated brim that provides very good protection for the head and face. Using the sliders on the waterproof zipper, you can adjust the breathing opening exactly as needed, allowing you to stay well protected from bad weather while reducing moisture build-up inside the bivy bag.
