Overboard TREKDRY™ Waterproof Backpack

Go anywhere and do anything without worrying about your gear with the VeloDry® Waterproof Backpack 20 Litres. Now you can stay visible and keep your stuff dry with this 100% waterproof backpack which includes our patent pending DualVis™ removable and interchangeable reflective or hi-viz front panel.

The VeloDry® Waterproof Backpack 20 Litres comes with a newly developed Pinch & Fold sealing system to ensure it provides 100% protection from water. You can even submerge the backpack completely to depths of up to 1m / 3ft for up to 30 mins, so no matter where you are or how wet you get, your gear will always stay dry.

And because it’s constructed from double-laminated reinforced PVC tarpaulin, this is one backpack that is built to last. It’s as durable as they come, and it also comes with useful features like the large internal zip pocket, extra-large side pockets, removable padded hip belt with quick access pockets and padded straps with improved air-flow design.

So get your hands on the VeloDry® Waterproof Backpack 20 Litres and protect your gear wherever you go.
