The design, materials, and features are exactly the same as those of a sports water bottle, but in reality, Byasi is a water bottle tool container. Practical and suitable for any water bottle holder, Byasi offers a compact solution for storing all the items you need during your bike rides, such as mobile phones, maps, masks, gloves, power banks, keys, sunglasses, or small maintenance tools for your bicycle. With a compact and sleek design that adapts to any route on road, gravel, and mountain bikes, Byasi is also waterproof and guarantees maximum protection for your items on the bike, thanks to the water- and rain-resistant material. Byasi has a standard diameter of 74 mm and is compatible with standard bottle holders.
