NeoAir Xtherm Large

When it comes to ultralight sleeping pads, the Therm-a-Rest NeoAir XTherm Ultralight Backpacking Air Mattress offers the most warmth-per-ounce for backcountry pursuits. Trusted by mountaineers worldwide, the XTherm delivers lightweight packability, boasting a 6.9 R-value for year-round warmth (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). Proprietary reflective ThermaCapture technology traps radiant heat within the pad, while the Triangular Core Matrix minimizes heat loss during sleep. Baffled internal structure provides support and comfort in a 2.5-inch inflated mattress, for a restful night in the backcountry. The two layers of triangle baffles create hundreds of individual cells to retain warmth and protect from the cold. Available in two styles: Equipped with the Standard Valve, or equipped with the WingLock Valve which is able to inflate a pad three times faster than a standard valve thanks to a larger barrel and optional one-way inflation.
