It’s all in the name – this is a pack for multi-day mountain bike trips – specifically the trans-alps but of course it won’t implode if you take it over the South Downs Way. 

There is built in back-ventilation, and female specific fit with adjustable straps and rails so you can get the fit just right for you.

A rain cover and reflective print mean you should be sorted in dark and damp conditions, plus helmet holder and plenty of internal zips for valuables.

This pack is compatible with a hydration system, and there is also a special compartment for any damp or smelly bits of kit you don’t want floating around.

The fabric is designed to be hard-wearing and water resistant, with a waxy, shiny surface. You can fit in 26 liters of kit – so you’re main worry will be avoiding over packing for your next trip.
