Go Lighter. Sleep Warmer.
Meet the ATEPA GridX 7.2 — the ultralight, high‑R‑value air mattress built for serious cold‑weather adventurers. At just 1.57 lbs and packing down to 10.24″ x 5.5″, it delivers exceptional warmth without the weight. Whether you're winter backpacking, alpine camping, or chasing seasons in the backcountry, the GridX 7.2 keeps you comfortable well below freezing.
Built for Extreme Conditions:
🔥 R‑Value 7.2 – Engineered for Sub‑Zero Nights
Rated for temperatures below ‑20°C (‑4°F). The advanced 9‑layer HeatLock construction—alternating aluminum foil, TPU, and durable fabric—creates isolated air chambers that trap heat and block cold from the ground.
⚖️ Ultralight, Not Ultracold
Weighing only 1.57 lbs, it’s one of the lightest winter‑rated pads on the market. Stuff it into your backpack and hardly notice it’s there — until you need its warmth.
🛏️ Vertical Tube + Dot Grid Design
Vertical air tubes paired with a textured dot‑grid surface provide enhanced support and stability, preventing that “rolling‑off” feeling and reducing contact with cold, uneven ground.
🧩 All‑Season, All‑Terrain Ready
From snowy peaks to rocky trails and sandy beaches, the 20D nylon TPU shell is puncture‑resistant and PVC‑free. The 3.94″ thickness cushions you from bumps and roots, so you wake up ready for the next adventure.
