Geometrically built to be stable when running on hills. The Classic has a closed-cell EVA padded shoulder harness specially constructed without side seams to allow the pad to follow the body’s natural contours. The waistbelt can be used to move weight onto the hips with heavier loads or removed for a faster, lighter shoulder carry option.

A good Mountain Marathon team will take advantage of the all round stretch mesh pockets on the Classic.
They stash their quick access kit such as waterproofs, food & water in their partner’s pockets so they can run behind and select what they like.
For the rest of us this means easy to reach stretch side pockets that will easily hold two bottles each and a rear stash for dirty trainers after a run or anything else that can stand a bit of weather.
The lid strap can be moved to attach at the top of the pocket for even more stretch volume. Up front the waistbelt pockets total 2L capacity and have key clips so phones compasses favourite goodies- it’ll all go
Designed both for multi-day outings and daily training. The Classic pack comes with a variety of attachment points depending on what kit you need to take.
Add the Chest Pod and front bottle holders for multi day ultra racing.
Or for winter ascents ice axes or walking poles can be attached to the gear rail when needed.
