The Trailvent 15 from Vaude is a compact and well-equipped backpack for biking and mountain biking. Its robust and weatherproof main material is made from recycled nylon. For maximum carrying comfort, it features anatomically shaped ErgoShape shoulder straps, an ideally ventilated Aeroflex 3D mesh back, a padded hip belt with pocket, and an adjustable back length. Looking inside the Trailvent 15 reveals a thoughtful compartment layout with an inner zippered pocket in the main compartment and an outlet for a hydration system. Additionally, there are practical mesh side pockets and an organizer in the front pocket. Bike-specific features include a holder for a bike pump and attachments for a helmet and rear light. The Trailvent is even more versatile and secure thanks to the compression straps on top and the reflective elements for visibility on the go.
