Boat trips, jetski sessions, fishing or kayaking. If you’re doing any of these things you’ll need a surf backpack that stands up to not just showers, but proper submersions. This is that bag. The Creatures S-Lock Dry Bag is rated at IPX8 Waterproofing. That’s a fancy way of saying it will go 1.5 meters underwater for half an hour without any moisture getting in. There’s 35L of space which is plenty to stuff in a couple of towels, spare clothes, shoes, your phone, and maybe a couple of tins of beer. 

The name of the bag comes from the triple-lock seal that needs to form an S shape to open it. It also has a roll-top and clip for even more waterproofing. The moulded back panel and straps keep things super comfortable to carry, and the actual material is a rugged TPU like the SAS use to make inflatable watercraft. In short, it’s tough, functional and built to last. In all black, it looks pretty stealth too.
