Sea to Summit UltraLight Self Inflating Mat Small orange

A self-inflating mat engineered for weight-conscious backpackers who need reliable insulation and packability in a single-season-spanning design.

The Sea to Summit UltraLight Self Inflating Mat uses Delta Core-V foam technology to remove material where it isn't needed, concentrating support and insulation at body-contact points. With an R-2.6 rating, it covers late spring through early fall conditions. The 30D woven polyester face fabric keeps weight low without sacrificing durability.
