The OMM Classic 25 Running Backpack is a highly versatile rucksack, ideal for a wide range of activities. The light weight is achieved without strength loss by means of the OMM Leanweight™ chassis. OMM backbacks feature a unique method of customisation and stripping OMM Adventure Packs to their minimum LeanWeight. In the Classic 25 Backpack, the back padding can be removed for a lighter weight, and can also double up as a sleepmat or sitpad.

The backpack features OMM's OTMA (On the Move Accessibility), giving you speed and efficiency on the hill. All your items are where you want them, in easy-to-reach places so you can focus on your training. The OMM leanweight link system has 4 discreet or semi hidden link points on almost all packs.
