Ultralight, Ultracompact, Backcountry Gear

Built for remote travel — ultralight, packable gear that fits your backpack and takes you beyond the trail.

We believe adventure means more when it’s shared.

We design lightweight, compact gear in Poland for people who move beyond the trail. Built to go far. Built to last.

Tested by hikers, paddlers, and mountain people who care more about the journey than the noise around it.

Less weight. More freedom. Nothing unnecessary.

MROZY is a growing community across Europe choosing simple movement and purposeful travel.

Move light. Move together.

Wojtek Surdy

Designer and inventor of the BACKWARDS binding system. Founder and co-owner of the company behind it. The whole idea came from pushing for simpler, smarter solutions in outdoor and adventure gear.

I also worked as Technical Director at Aerosize R&D, where I focused on research and development for avalanche safety technology.

Most of my professional life is about designing and building equipment for demanding outdoor conditions — stuff that has to work in the cold, in the mountains, and when things don’t go as planned.

Friends

We actively collaborate with people we know and trust — friends, designers, riders, and industry partners. We work closely together, test gear side by side, and sometimes turn these collaborations into long-term projects or real products.
