Ortlieb

Ortlieb makes waterproof storage gear for the outdoors, built to be tough and hard wearing. The range covers dry bags, pouches, map cases, water sacks and travel gear, and Taunton Leisure, an independent outdoor specialist, describes it as some of the strongest kit on the market. The dry bags come in a variety of sizes.

You could buy a cheaper map case or dry bag, but the retailer's view is that an Ortlieb will outlast the alternatives many times over. That toughness has made the dry bags popular with forces personnel. Working Class Heroes also stocks a men's range.
