Classic 18

First developed in 1973 to a specification set by Olympian and later London Marathon founder Sir Chris Brasher, The Classic was the first pack to look at weight as a key part of a bag’s functionality.
This is a smaller capacity version of the already popular latest iteration, suited to smaller frames or those looking to strip their Mountain Marathon Kit to the minimum.
The Classic range balances weight, accessibility on the move, comfort (at all speeds of movement) and multi-function componentry.
This is the pack that just works. Perfect for an OMM but also at home on something easier like the MDS, UTMB, Spine Race, Dragon’s Back, Grand2Grand, 4 Deserts, Fire Ice Ultra, or Everest
It just does everything really well. It’s a Classic.

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 in.
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.
Strip off the back padding and waistbelt for a super light dash bag.

Backpack or RaceVest?

And when is a backpack a vest!? A backpack normally uses a more traditional shoulder strap system, alongside a waistbelt and/or sternum strap fro stability. A vest is more like a piece of clothing, with fabric wrapping around the torso, both for stability and also allowing for extra pockets and storage. Backpacks are generally suited to larger loads as they can have more padding on the straps and weight through the waistbelt. However, the benefits of a racevest, with its accessable storage on the move, we have tried to incorporate some of those features, alongside the fit and stability to larger loads in order to create VestPacks such as the Phantom 25.

Can I Wash My Backpack?

 Yes! Its a good idea to occasionally wash away all that sweat, dirt and oil that accumulates through regular use of your Backpack. Just check all the pockets for forgotten jelly babies and fivers, undo the zips and remove any foam padding from the back system plus any other removables such as pegs. Use a quick cycle and a specific outdoor wash then line dry; done! More Info Here

Men's & Women's Backpacks?

 Nope! Since all our backpacks are designed for running, they ride high on the back away from the running motion of the hips. This means back lenths is less of an issue and we are able to have a good degree of adjustability, to suit a range of body shapes, in the harness and shoulder straps. Some of our larger backpack sizes are better suited to larger frames, such as the Classic 32 whereas the smaller Phantom 18 would be a good choice for a smaller frame but they are both unisex.

What's the volume?

 The number quoted after most of our backpacks denotes its total volume, though stretch mesh panels and waistbelt pockets usually add a little extra to that total!
