Precision-Engineered Warmth. The 3.94-Inch Pad That Masters Weight, Warmth, and Packability.
The ATEPA EdgeX 5 redefines cold-weather comfort for the weight-conscious adventurer. With a premium R-Value of 5.0 and a precise 3.94-inch (10 cm) loft, this pad provides the perfect balance of plush cushioning and reliable thermal insulation for winter excursions and demanding three-season trips—all while maintaining an ultralight profile and a pack size smaller than a standard water bottle.
Engineered for Superior Performance in Demanding Conditions:
✅ CERTIFIED COLD-WEATHER INSULATION (R-VALUE 5.0)
Constructed with a 6-layer internal thermal matrix, including aluminum-coated films and vertical air tubes, the EdgeX 5 effectively reflects body heat and minimizes conductive heat loss. Rated for temperatures down to -4°F (-20°C), it provides dependable protection from frozen ground, making it a versatile choice for alpine trails and late-season camping.
✅ OPTIMIZED 3.94-INCH SUPPORT & COMFORT
Experience targeted comfort with a substantial 3.94-inch (10 cm) thickness. The vertical segmented baffle design delivers superior body support and stability, effectively eliminating pressure points and the sensation of touching the ground, even on rough, uneven surfaces.
✅ ULTRALIGHT EFFICIENCY WITHOUT COMPROMISE
Achieving a best-in-class weight-to-warmth ratio, the pad itself weighs just 1.48 lbs (670g). It compresses to an ultra-compact 5” x 5” x 10”, maximizing space in your backpack for other critical gear—a true advantage for long-distance backpackers and fast-and-light missions.
