Mountain Spring Ultralight Multi-Purpose Ground Sheet

A new take on the camp mat: a thin, closed-cell TPE sheet that lives under your air pad or wherever you need a clean, dry, grippy layer. It packs far smaller than a classic “egg-crate” foam, rides inside your pack (no more dangling bulk), and earns its spot on every trip.

Under your air mat: adds a closed-cell layer to boost warmth, blocks ground moisture, stops your pad from creeping on sloped terrain, and cushions against thorns, gravel, and rough sites to reduce punctures.

• Tiny pack size: folds or rolls into a compact brick—much smaller than foldable foam—so you don’t need to strap anything outside your bag.
• Multi-use in the field: deploy as a sit/kneel pad for breaks and camp chores, a clean vestibule floor, a quick picnic or stretch mat, or roll it into a cylinder to line your pack and protect fragile gear.
• Travel-ready beyond the trail: in hostels, refuges, or huts, lay it on public bunks for a quick clean barrier that also helps against damp.
• Built to last: closed-cell TPE is non-absorbent, abrasion-resistant, and easy to wipe clean; the grippy texture stays put while the elastic rebound keeps it flat trip after trip.

Always dry, always simple: fully waterproof, quiet in use, and intuitive to deploy—no valves, no fuss. Innovation you feel immediately: warmer sleep, cleaner breaks, fewer pad punctures—without the bulk of traditional foam.
