The OMM Ltd Classic 18 was originally designed in 1973 by Olympian and London Marathon founder Sir Chris Brasher, it was the first lightweight backpack that focused on weight as a key feature. Perfect for mountain marathons like the OMM, it’s also ideal for endurance challenges like the MDS, UTMB, Spine Race, Dragon’s Back, Grand2Grand, 4 Deserts, Fire Ice Ultra or even Everest expeditions.

The OMM Ltd Classic 18 is the ultimate lightweight backpack for outdoor enthusiasts who value speed, comfort and functionality. Designed for smaller frames or minimalist setups, this compact version of the popular Classic series is perfect for mountain marathons, trail running and multi-day adventures. Engineered for peak performance on rugged terrain, the Classic 18 ensures stability and comfort at any speed. Its geometrically balanced design includes a closed-cell EVA padded shoulder harness, crafted without side seams to naturally conform to your body. The removable waist-belt lets you adjust your load - you can shift weight to your hips for heavier gear or go ultralight by carrying on your shoulders alone.

Stay organized and efficient on the move with the Classic 18’s innovative storage system. The all-around stretch mesh pockets offer quick access to essentials like water bottles, food and waterproofs. Side pockets can easily hold up to two bottles each, while the rear stash pocket is ideal for storing muddy trainers or weatherproof items. For added versatility, the adjustable lid strap expands the pack’s capacity. The 2L waist-belt pockets include key clips for secure storage of phones, compasses and snacks.

Adapt the Classic 18 to meet the demands of your journey: Add a Chest Pod (see related items) or front bottle holders for ultra-marathon races, or attach ice axes and walking poles to the gear rail for winter ascents. Need a lighter pack? Remove the back padding and waist-belt to transform it into a sleek, fast bag for short-distance adventures.
