Original Mountain Marathon (OMM) performance gear

The Original Mountain Marathon (OMM) brand is a legendary name in the world of extreme outdoor sports, rooted in the heritage of one of the world's first and most demanding mountain endurance races. Originally known as the Karrimor International Mountain Marathon, the brand evolved to produce specialized high-performance equipment designed for trail running, mountain marathons, and fast-packing.

OMM's product philosophy focuses on ultra-lightweight design and durability, tailored to survive the harsh conditions of the British uplands. Their range includes technical waterproofs, hydration packs, and sleeping systems. While the brand is quintessentially British in its design and testing phases, manufacturing is distributed globally across several countries to utilize specialized technical textile facilities.

Ownership of the OMM brand transitioned away from the original Karrimor entity several decades ago. Today, it remains an independent and specialist brand focused on the niche endurance community. The brand continues to facilitate and sponsor the eponymous annual race, ensuring that their product development remains directly connected to the needs of elite athletes and mountain enthusiasts worldwide.
