Cold-Weather Certified. Ultralight Engineered. Sleep Anywhere.

The ATEPA CoreX 5 delivers serious winter-grade insulation in a featherlight package. With an R-Value of 5 and a weight of just 600g (1.32 lbs) , it's engineered for backpackers and adventurers who demand reliable warmth without the bulk. Rated down to -4°F (-20°C) , this pad keeps you comfortable on snow, frozen ground, and chilly alpine campsites—while packing smaller than a water bottle.

Key Features:

✅ R-VALUE 5 – TRUE 4-SEASON INSULATION
Certified to R-Value 5 with 7-layer thermal core technology. Heat-reflective films and multi-chamber construction trap warmth and block ground cold. Sleep warm in conditions from summer nights to deep winter.

One of the lightest high-R-value pads available. Shed pack weight without sacrificing warmth. Ideal for thru-hikers, alpine climbers, and ultralight purists.

✅ 3.54" THICKNESS – ROCK-PROOF COMFORT
9cm of loft fully elevates you from rough terrain. No more feeling roots or rocks. The horizontal tensioning system provides stable, body-mapped support that prevents sagging and keeps you comfortable all night.

✅ INTEGRATED PUMP SACK – NO LUNG POWER NEEDED
The included storage bag doubles as a dry inflation system. Just roll to inflate—no moisture inside, no lightheadedness. The dual-layer valve delivers one-way inflation and rapid deflate in seconds.

Rolls down smaller than a 1L bottle. Fits easily in any backpack.
