Keep your feet warm and comfortable in alpine huts, base camps, and cold bivvy spots with the Mountain Equipment Superflux Hut Slipper. Designed for high-mountain practicality, these ultra-lightweight and highly packable slippers offer reliable insulation and slip-resistant stability when the climb is over.

The Superflux is built with POLARLOFT® Featherless synthetic insulation—a down-like alternative that performs exceptionally well in damp, cold conditions. Wrapped in Mountain Equipment’s Helium™ 20D outer fabric, the slipper offers a superb balance of warmth and durability with minimal bulk. Whether you're sheltering in a winter hut or winding down at altitude, these slippers lock in heat while allowing your feet to breathe.

Inside, a brushed lining provides a soft, cosy feel against the skin, while the low-profile construction makes them easy to slip on and off. The rugged, slip-resistant sole ensures secure footing on hut floors or frosty decking, and their compact design means they pack down effortlessly in your duffel or rucksack.

• Winter mountaineers and alpine trekkers
