The POC Ultra Bar Bag 4L mounts at the handlebars for the gear you want to reach without stopping. It suits bikepacking and long gravel days where a jacket, food and a camera need to be accessible. The bag uses a robust waterproof X-Pac material with a waterproof double zipper, so it holds up to sustained weather and abrasion. Internal mesh pockets keep small items from disappearing into the bottom, side mesh pockets take a phone, and adjustable elastic straps make mounting and removal quick across different bar setups.
