The largest of our dry cylinder bags, this 50 litre sack offers a compact solution to ensure your gear and valuables are kept dry and secure while out on the water. Made from puncture resistant, fully waterproof PVC tarpaulin fabric with a stitch -free welded construction, the flat base allows it to stand freely, ideal for upright storage. The roll-down closure offers a complete watertight seal while the handy semi-transparent mesh-reinforced window allows you to easily see the contents inside.
