Oxford Aqua Luggage M8 Tank Packs are made from a tough PVC tarpaulin, which is welded to form waterproof seams. When straps are added to perform essential functions (such as securing the bag onto a motorcycle), Oxford uses innovative construction techniques to further reinforce the bag whilst ensuring complete waterproofing. The latest generation of Oxford’s acclaimed Aqua luggage now offers a choice of five useful tail bag sizes - from commuter 8L through to ‘epic voyage’ 70-litre versions – plus a range of backpacks and tank bags. Features: Waterproof roll-top closure. Wipe-clean, waterproof construction with welded seams. Large, clear 170mm x 90mm touch-compatible window with a deep pocket behind. Water- resistant zip. Moulded easy grab carry handle. Reflective detailing. Headstock strap included (must be used). Approx size when filled: (HxWxD) 30 x 18 x 12cm
