Oxford's Aqua Bags are one of the easiest ways to get your gear from A to B, safe and dry. They are made from tough PVC tarpaulin, which is welded to form waterproof seams. Small is beautiful... this compact matching tank bag complements Oxford's best-selling range of Aqua Roll Bags. This tank bag uses powerful magnets to attach onto steel tanks and has a clear pocket large enough for the biggest mobile phones. Its waterproof construction means contents are kept safe in any weather and the roll-top design with compression straps allows you to adjust its size to fit exactly what you need to carry.
