Following years of product development and countless hours of practical experience with this spacious pack, the Trans Alpine now counts as one of the most sophisticated bike backpacks on the market and the number 1 choice for alpine traverses by mountain bike. The clever layout, with tool and pump compartments, for instance, plus a handy front stash pocket which can also accommodate a helmet, and a subdivided main compartment give this pack the kind of easy handling and clever organization you need on multi-day routes.
