Foot Warmers

Compact | Ultralight | Reliable

Fill the FootWarmers with warm water, slip them onto your feet and get into your sleeping bag. Enjoy warm feet all night long

Idea of Piotr Krzyżowski – high-altitude mountaineer. 11× 8000m peaks: K2, Everest, Nanga Parbat, Makalu, Lhotse, Manaslu, Dhaulagiri, Kangchenjunga, Broad Peak, Gasherbrum I & II. 

FootWarmers are compact, expedition-grade heat pouches designed to restore warmth to frozen feet after long days in the mountains.

Made from durable, welded waterproof material, each FootWarmer functions like a small, sealed hot-water cushion. Simply fill it with warm water, close it securely, and slip it over your feet or place it inside your sleeping bag. The shape is optimized to wrap around the toes and forefoot, delivering direct, comforting heat exactly where climbers need it most.

After a summit push, winter hike, or long cold exposure in the alpine zone, FootWarmers help bring back circulation, relax frozen muscles, and make it possible to fall asleep faster in extreme conditions. Once inside your sleeping system, they continue to release stored heat for hours, helping maintain warmth deep into the night.

Lightweight, packable, and reusable, they are built for mountaineers, winter trekkers, and anyone who needs reliable warmth in harsh environments—when cold is no longer just discomfort, but a real limiter of recovery.

Simple. Effective heat when everything else is frozen.
