Sea to Summit UltraLight Self Inflating Mat Large orange

A self-inflating mat engineered for ultralight backpacking without sacrificing insulation or packability.

The Sea to Summit UltraLight Self Inflating Mat (Large) is built for minimalist hikers who need the reliability of self-inflating foam in a compact package. Delta Core-V™ technology varies core size across the mat — smaller vertical cores at shoulders, hips, and feet for targeted insulation, larger cores elsewhere to cut bulk. An R-value of 2.6 and 198 × 64 cm coverage make it a capable three-season option.

Features

• Anti-slip print on base keeps the mat stable on uneven or sloping ground
