Silent. Slim. Sealed. Your bike’s secret weapon for carrying smart.

This is the bag you forget is even there—until you need it.

Tucked inside your bike’s triangle, the F01 Waterproof Frame Bag puts your heaviest, most essential gear exactly where it should be: low, stable, and dry.

Built from recycled, military-grade fabric and sealed with high-frequency welding, this 3L workhorse is waterproof, universally mounted, and made to ride through anything.
