Sea to Summit Pursuit SI Mat - Large Rectangular Wide bombay brown

A self-inflating mat built for alpine touring and multi-day backcountry use where reliable rest is essential.

The Sea to Summit Pursuit SI Mat uses Horizontal Delta Coring — 5 cm foam-supported air channels — to balance comfort and insulation without excess bulk. The XPEL Multi Function Valve simplifies inflation, fine adjustment, and deflation, while the side-loading stuff sack speeds up pack-down. Fabric is bluesign APPROVED, RCS-recycled, and solution-dyed with a non-PFAS finish.
