Sea to Summit Ultralight Self Inflating Mat

The Ultralight Self Inflating Mat is the lightest and most packable self-inflating sleeping mat Sea to Summit offers, coming in at just 1 inch thick and 520-550 g. This mat is perfect for minimalist campers, hikers, and backpackers who want more comfort than a roll mat but want to save as much space and weight as possible. Weight is kept to a minimum through Delta Core-V™ vertical coring, which removes unnecessary areas of foam to improve packability and reduce weight without affecting comfort and support.

Features:

- Utilizes 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 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
