The newest addition to our lineup is the self-inflating S.I. Mat, a series that offers even greater comfort with a different structure than our traditional 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 is 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. Fine-tuning the firmness is possible 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. The BodyZone die-cut foam structure is optimized to protect the shoulders and lower back from the cold. Other areas are cut larger to reduce weight. The multi-functional, large-diameter valve with a double structure and durable 75D fabric make it easy to inflate and deflate.
