OverBoard is famous for making waterproof gear in all kinds of forms, from small phone cases to large sports bags - and here in the form of the excellent Overboard Backpack, it might just be having its finest hour. This Premium Waterproof Backpack comes in either 20 or 25-litre capacity. You get heat-welded seams, a two-way roll-top closure system and plenty of adjustable padded straps to keep you well supported and comfortable. There is useful back venting to help keep sweat at bay and an attention to the small details you rarely find on a dry bag. It’s astonishingly good value and, as a means of keeping your gear free of water, dust and sand, it’s about as good as we’ve ever seen.
