When it comes to wash bags, we're big fans of keeping it simple. Take this colourful dopp kit from Cotopaxi, for example. It offers a roomy main compartment with a couple of internal side sleeves, a central zipper, and a webbing loop so you can hang it on the back of the bathroom door. Everything you need, and nothing you don't. Even better, Cotopaxi have chosen to make it out of remnant fabric that would otherwise have ended up in landfill. The durable nylon material is all left over from other companies' production runs, and each toilet bag is stitched together from different-coloured odds and ends – making every single one unique.
