Attention cyclists! With the Trailvent 20, Vaude offers a modern bike backpack that will impress you with its clever details. The centerpiece is the excellently ventilated Aeroflex 3D carrying system with adjustable back length, which, combined with the flexible padded hip belt, ensures a stable fit even when you're bouncing around during downhill rides or gravel biking. The compartment layout is equally well thought out, as the main compartment is designed for spare clothes, rain gear, and daily provisions, while the Trailvent 20 also features a front pocket that securely and neatly stores your bike tools and pump. For a quick energy boost in bar or gel form, you can use the small zippered pocket on the hip belt, and if you prefer a hydration system over a bottle, this bike backpack is equipped for a water bladder, including a hose outlet and attachment. True to Vaude's commitment to sustainability, the Trailvent 20 is no exception: it is made entirely from recycled and environmentally friendly dyed materials and is PFC-free with Eco Finish impregnation.
