Sea to Summit Ultralight Self Inflating Mat (Large)
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.
