The Women's Delta Core-V concept is simple: remove enough foam to cut down weight, leave enough foam to ensure comfort and warmth. The Women's UltraLight Self-Inflating Sleeping Mat is constructed with Comfort Warmth Zones in the hip foot and torso areas to provide extra support and insulation for the woman backpacker who wants to keep her load light. Silicone prints on the upper surface prevent your sleeping bag slipping, and the flip-over multi-function valve makes rolling up the self-inflating mat really easy.
