The Therm-a-Rest NeoAir XTherm Large is a lightweight sleeping pad designed for cold-weather camping. It’s made to offer insulation and cushioning between you and the ground, keeping you warmer when temperatures dip far below freezing.
Constructed with a 30D ripstop HT nylon top and polyurethane insulation, this pad delivers a comfortable 6.4 cm of loft while remaining compact in your pack. At 196 x 64 cm it provides generous sleeping space, yet it rolls down to just 28 x 11 cm and weighs 0.57 kg—traits that help keep your load light without sacrificing comfort or durability.
The NeoAir XTherm’s R-value of 6.9 reflects its high resistance to heat loss, making it suitable for conditions as cold as –31 °C. In simple terms, that rating means it does a strong job of blocking conductive heat transfer to the frozen ground, so you stay warmer through the night.
