Light and packable for minimalist fast hikes, the Ultralight Self-Inflating mats come in at 1 inch thick with the regular size weighing just over 1 pound. We keep the weight down by using a 30-D polyester and our Delta Core-V™ vertical coring which keeps body contact areas warmer while still offering great support and packability.

• Utilises Delta Core-V™ technology, which keeps body contact areas warmer while still offering great support and packability
• Multi-function, patent-pending multi-function valve twists over to allow the sleep mat to be rolled tightly without fighting re-inflation as you go
• At 1 inch thick and an equivalent R-Value of 2.6, the Ultralight SI Mat delivers a great weight to warmth ratio for minimalist hikers
