Kryos
Part of our Extreme Alpine sleeping bag range, the lightweight Kryos is designed for alpine expedition use and cold-weather trips where low weight and extreme protection are essential.
Combining exceptionally high-quality minimum 800-fill power goose down with a highly breathable and water-resistant DRILITE® LOFT 10 denier outer fabric, the Kryos thrives in remote cold environments and can easily cope with snow melt and condensation. For added protection, the DRILITE® fabric extends into the bag's hood, around the collar and in the foot box—all areas prone to dampness.
Trapezoid baffles optimally balance weight and pack size throughout the bag against warmth and down control. A complex seven-baffle system concentrates down in the hood and collar for optimum warmth and protection over long-term use. In comparison, in the anatomically shaped foot box, a six-baffle system focuses warmth around your feet. A full-length Gemini™ entry zip baffle reduces heat loss in this vulnerable area, and the low-profile magnetic Lode Lock™ closure and collar drawcords are easy to use in the dark or under challenging conditions.
Our extreme alpine bags have a tapered Alpine fit that can accommodate additional down layers and boots as necessary and allow seated or fetal-position sleeping on restricted bivy spots.
With a Good Night’s Sleep Temperature of -20oC, the Kryos is the warmest bag in our extreme alpine range. This rating, determined through exhaustive lab work, countless field trials, and thorough expedition testing, indicates the minimum temperature at which we feel an experienced user will be comfortable in this bag in real-life situations.
