Air Sprung Cell UL Mat

For the absolute ultralight minimalist, Sea to Summit's Air Sprung Cell UL Mat offers a barely-there solution that still provides a noticeable step up from a foam pad. This uninsulated pad is designed for warm weather or for layering with a closed-cell foam pad in cooler conditions, reflected in its R-value of 0.7. Its core innovation lies in the single layer of Air Sprung Cells, which provide a surprising amount of stability and comfort for their minimal weight. At 2 inches thick, it keeps you off the ground, and the 20D ripstop nylon fabric is surprisingly durable for its weight class, though care is still needed. It packs down incredibly small – arguably one of the smallest packed sizes on this list. Inflation is via the integrated Airstream Pump Sack in the stuff sack, making it quick and moisture-free. This pad isn't for everyone; its lack of insulation is a significant factor, but for those counting every gram on a summer thru-hike or warm-weather trip, it delivers the lightest possible comfort from an inflatable pad. **Highlights** * Extremely lightweight and compact for ultimate ultralight backpacking. * Air Sprung Cell technology provides surprising comfort and stability for its weight. * Integrated Airstream Pump Sack for easy, moisture-free inflation. * Durable 20D ripstop nylon fabric. * 2-inch thickness keeps you off the ground. * Ideal for warm weather or as a comfort layer over a foam pad. **Watch-outs** * Very low R-value (0.7); only suitable for warm weather. * Thinner fabrics require careful use to prevent punctures. * Not designed for cold weather unless paired with another pad.
