When staying warm is as important as keeping your pack light, the Thermarest ProLite Plus mattress is the perfect solution. Using patent-pending foam-perforating technology, we’ve created this mattress to provide exceptional warmth—up to 20% more than previous ProLite 4 mattresses—without added weight. It’s substantial enough to keep you comfortable while mountaineering or on ski tours, yet rolls up small and light enough that you’ll have no problem taking it as far as you want to go.
Added Warmth:
Unique, diagonal-cut foam provides the most efficient insulation possible.
Light and Compact:
Tapered design and high-performance foams eliminate excess weight and roll up ultra-compact.
Rest Comfortably:
Bottom grips and textured top surface keep the mattress where you want it while you sleep.
