WELCOME TO OUR WORLD

OMM products are built to withstand the toughest conditions faced by mountain runners – designed for and tested by the competitors of OMM’s namesake event: The Original Mountain Marathon.

Held in unforgiving conditions of the UK fells at the end of October, the event demands endurance, self-reliance and gear you can rely on.

CREATED FOR TOUGH CONDITIONS

We create innovative, reliable & sustainable gear because hard-earned miles in all kinds of weather demand gear that keeps up. We want our clothing and equipment to provide ultra-light, weather-resistant protection without compromising movement. Because when you challenge runners to survive two days in the mountains with everything on their backs? You end up creating gear that works.

Est. 1968

The Original Mountain Marathon, previously named KIMM, was created as the ultimate test of self-reliance, navigation, and a healthy dose of mountain respect – turns out they were onto something.

50+ Years Of Events

For over 50 years, October has meant one thing – mountain marathon time. Through rain, gales, and whatever else the British weather throws at us. Only a pandemic and one properly angry storm have ever made us skip a year.

The Event Behind the Gear

When the existing kit didn’t cut it, we made our own. Based on the unique needs for ultra-light gear that can withstand the toughest conditions, the OMM product range was born.

Used On The Toughest Challenges

Dragon’s Back veterans and first-time fell racers have one thing in common – they trust our gear when the going gets vertical. Whether you’re racing across Wales or charging up your local peak, reliable kit makes it more enjoyable.

Continuing The Tradition

Fifty-plus years of sending pairs into the peaks with nothing but their wits and what they can carry on their backs. Some traditions fade, but the art of getting gloriously lost in the mountains… That’s timeless.

Gear That Out Lasts Trends

We build gear that sticks around longer than your Strava records. Every piece is designed to take a beating, be repairable, and keep performing season after season.

OBSESSED BY DETAIL

Mountains don’t do standing still, and neither do we. Every piece of OMM gear is engineered for movement – from race vests that don’t bounce on technical descents to layers that stretch in all the right places. We obsess over the details that matter: zip pulls you can grab with cold hands, pockets you can actually reach while running, and fabrics that work as hard as you do. Because when you’re halfway up a mountain, the last thing you need is your gear holding you back.
