Klymit KSB 0 Synthetic

Klymit says:
Designed for the rigors of all four seasons, the KSB 0u Synthetic sleeping bag is warm, lightweight, and ideal for mixed conditions. Warm and durable, the Klymalite synthetic fill insulates even when wet. A draft collar, over-stuffed foot box, insulated mummy hood and flexible baffles at the bodyOs core all work together to minimize heat loss for greater thermal efficiency. High tenacity fabrics are tough, light and comfortable. The expanded chest area and flexible baffles provide room to move, and a stash pocket keeps small items right at hand. Paired with one of our Inertia or Static pads, it becomes a highly efficient, exceptionally comfortable backcountry sleep system.
