Using patent-pending technology to create warmth without the weight of conventional insulation, Therm-a-Rest NeoAir technology is a result of over seven years of product development.
The term R-value as used in relation to sleeping pads is a measurement of the ability of the mattress to retain warmth. The higher the R-value, the warmer the sleeping pad.
With an ultra-lightweight design, the Therm-a-Rest Women's NeoAir XLite inflatable sleeping pad is built for ounce-counting backpackers.
The warmest offering (5.7 R-value) in Therm-a-Rest's innovative line of inflatable mattresses, the NeoAir XTherm is a lightweight, packable option for cold-weather and year-round use.
