Sea to Summit Pursuit Self-Inflating Sleeping Mat – Large, 78 x 25 in | Lightweight, Three-Season Comfort

Lightweight comfort for backpacking and camping

The Sea to Summit Pursuit Self-Inflating Sleeping Mat — Large is designed for hikers and campers who want a compact sleep solution without sacrificing comfort. Measuring 78 x 25 inches with a slim 2-inch thickness, it remains remarkably light at about 1.61 pounds, making it one of the lighter options in its class for three-season use. An ASTM-tested R-value of 3.0 provides a solid warmth baseline, so you can rest more soundly on diverse terrains and conditions without carrying extra bulk.

Materials and sustainability you can feel confident about

The mat is built with bluesign APPROVED, RCS-recycled, non-PFAS, solution-dyed fabric. This combination supports durable performance while emphasizing responsible design and reduced environmental impact. The thermally efficient contour targets support where you move most—side sleeping and shifting through the night—so you can sleep with less fuss in the tent or under open skies.

Smart design for comfort and easy setup

Horizontal Delta cores create air-filled chambers that help distribute air evenly and reduce bulk, so you get more cushion without adding weight. An XPEL multi-function valve makes inflation, adjustment, and quick deflation simple, and the side-loading stuff sack ensures packing is fast and tidy after a long day outdoors.
