The Birzman Feexroll tool bag is a practical companion for cycling tours. Made from water-repellent material, the bag can be mounted under the saddle. The rollable bag features several inner pockets for individual items, keeping the tools well organized. It has space for items such as a mini tool, a spare tube (depending on size), and a CO2 cartridge with inflator. The bag can be rolled up and secured to the saddle rails with Velcro, making it easy to switch between different bikes.
