Lightweight Warmth for Cool‑Weather Adventures.
Meet the ATEPA GridX 6.8 — the versatile, high‑R‑value sleeping pad built for backpackers and campers who push into shoulder seasons and mild winter conditions. Weighing just 1.5 lbs and packing to the size of a standard water bottle (10.24″ x 5.5″), it’s the perfect balance of warmth, comfort, and packability for three‑season trips and chilly winter nights.
Engineered for Comfort in the Cold:
R‑Value 6.8 – Ready for Cool to Cold Conditions
Rated for temperatures from 0°C down to ‑20°C (32°F to ‑4°F), this pad provides reliable insulation for spring, fall, and mild winter camping. Its 7‑layer HeatLock construction — alternating aluminum foil, TPU, and durable fabric — separates each air chamber to minimize heat loss, so you stay warm without carrying extra weight.
Ultralight Design, Real Warmth
At 1.5 lbs, the GridX 5.5 is one of the lightest insulated pads in its class. It fits easily in your pack and sets up fast, so you spend less time managing gear and more time enjoying the outdoors.
Vertical Tube Support + Dot‑Grid Surface
Vertical air tubes work with the dot‑grid texture to increase stability and support, reduce ground contact, and prevent slipping — so you sleep soundly on uneven terrain.
🧩 Durable & All‑Terrain Ready
Made from tough, PVC‑free 20D nylon TPU, this pad stands up to rough ground, rocks, and sticks. The 3.94″ thickness cushions you comfortably, whether you're in the backcountry, at a campground, or using it as a guest bed at home.
