Simplistic and lightweight reliability, lightweight hikers will love the Sea to Summit Ultra Light SI self-inflating mats. There is nothing particularly revolutionary about these mats, but they do come from an innovative company with a strong history in product reliability.

Heat mapped Delta Core-V™ PU Foam has variable sized vertical cores to provide insulation where it is needed and trim weight where insulation is not necessary. The exterior is a lightweight 30D polyester that provides a great balance between the wishes of lightweight trekkers whilst withstanding the rigours of outdoor use.

An anti-slip print on the base helps keep the mat in place if your campsite happens to be a little sloped, and the multi-function valve makes set up and pack down quicker and easier than ever. The STS Ultra Light SI hiking mats are a reliable and affordable sleeping option for fast-paced adventures.
