For sleep-anywhere comfort, the Therm-a-Rest Z Lite Sol mattress is a light, compact, full-length closed-cell foam sleeping pad that features a heat reflective surface for added warmth.

  • Features

    • Aluminized surface reflects heat, returning it back to your body; increases overall warmth from previous model by nearly 20%
    • Pad is engineered for extreme alpine climbing, adventure racing and long-distance backpacking when reducing weight is paramount
    • Egg-carton pattern increases softness and adds insulation by trapping warm air under your sleeping bag
    • This pad has an R-value of 2.0, which makes it best for adventures in cool weather; it provides moderate insulation from ground temperature
    • Most sleeping pads we sell range from 1.0 (good for warm weather) to 5.5+ (for use in extreme cold); the higher the R-value, the more insulated the pad
    • Therm-a-Rest Z Lite Sol mattress uses an accordion-style design that lies flat instantly and folds up into a small package quickly and easily
    • Closed-cell foam withstands years of use and abuse

    Made in USA.
