SEA TO SUMMIT Camping Mat S.I. (Regular) ST81105

The newest addition to the lineup is the self-inflating S.I. Mat, a series that offers even greater comfort with a different structure than the conventional air spring mattress series. The S.I. Mat camping mat series is ideal for cost-effective campers and trekkers. To reduce weight, the internal foam has been hollowed out according to body parts. The Sea to Summit Mat's greatest feature is its multi-functional, large-diameter valve, which makes it easy to inflate and deflate. Firmness can be fine-tuned with a single push, and by flipping the check valve when packing down, air can be prevented from re-entering, allowing for quick and compact folding. - BodyZone die-cut foam structure optimized to protect shoulders and waist from the cold. Other areas have been cut larger to reduce weight. - Double-walled, multi-functional, large-diameter valve - Durable 75D fabric Size: 183cm L x 51cm W x 3.8cm D / Regular Storage Size: φ16cm x 26cm / Regular Weight: 780g / Regular R-value (Thermal Resistance): Equivalent to 4.0 Accessories: Dedicated stuff sack
