The Ultra Light Collection is the lightest and smallest packable sleeping mat from Sea to Summit. The specially designed core reduces weight by 20%, while maintaining cushioning and support in key areas of the body. The BodyZone die-cut foam construction optimizes warmth in important parts of the mat while minimizing weight in other areas. An anti-slip print on the surface and bottom keeps the sleeping bag and mat in place. The multifunctional, high-flow valve allows for easy inflation, one-way deflation (ensuring the mat does not self-inflate while being rolled up), and fine-tuning for comfort.
