This is one of the core OMM products which was also previously know as the KIMM Sac 25. Having been in use since 1974 it is not surprising that this rucksack has such a strong following.

This pack is large enough to take all your gear on an OMM event. It is for these types of events where this pack excels. The packs comes as standard at a respectable 670g and like other OMM products there are elements of the pack that can be permanently removed, reducing the weight even more, to a potential 540g.

If keeping the weight down for climbing approaches, lightweight walking and of course running events, with a bit of a compromise to be taken due to minimal back padding, then this pack must surely be a contender.
