15L TPU Waterproof Cycling Backpack with Floating Ventilated Back System

Floating ventilated back — a suspended mesh panel channels air to cut back sweat.

Waterproof TPU + dual zipper — welded seams, IPX6, sheds rain, mud and splash.

Slim cycling fit — keeps the load close and stable while riding.

Full harness — padded straps, sliding sternum strap and waist belt.

Gear attachment + light 0.85 kg — clip on a helmet, pump or poles.

Floating Ventilated Suspension Back System

The back panel is a suspended, trampoline-style mesh that sits off the pack body, creating a ventilation channel between the backpack and the rider's back. Air flows through that gap as you ride, carrying heat and moisture away and cutting the sweat build-up that ruins a long ride against a flat back panel. It is the feature cyclists notice first — a cooler, drier back on climbs and in warm weather. (The "floating" back refers to this suspended airflow panel, keeping the pack off your back.)

Waterproof TPU, Welded, Dual Zipper

The body is durable TPU waterproof fabric — flexible and abrasion-resistant — welded into a seamless shell with no needle holes, and the main compartment closes with a waterproof dual zipper for easier two-way access while helping keep rain and splash out. Rated IPX6, it is built to keep gear dry through wet-weather riding; because it uses water-resistant zippers rather than a sealed roll-top, it handles rain and splash rather than submersion, and wipes clean after a muddy ride.

Ergonomic Cycling Fit

The pack has a slim, tall profile (27 × 18 × 50 cm) that keeps the 15L load close to the body and low-drag, reducing sway and improving balance when you are moving on the bike. It is shaped to ride, not to bulge off your back.

Full Harness: Sternum and Waist Straps

Wide padded shoulder straps spread the weight for long-distance comfort, a sliding sternum strap adjusts up and down to fit your torso, and an adjustable waist belt stabilizes the pack for mountain biking, commuting and trail riding — so the load stays put through rough sections and sprints.

Gear Attachment and Organization

An external gear-attachment system with multiple points lets you secure a helmet, jacket, pump, trekking poles or other kit to the outside, while an internal zippered pocket keeps a wallet, phone, keys and small accessories organized inside. Reflective detailing is available as an OEM option for low-light visibility.
