Shower tote

Wasroom > Bathing accessories > Portable > Bath carryall
At the gym or in a dorm, you have to use a public shower, and this means bringing your soap, shampoo, razors and whatever else you need with you. A shower tote is a practical way to do this. A ziplock bag may be almost as good, but if the interior gets wet, so will all your stuff. Mesh and plastic totes let any moisture evaporate and so your toiletries get dry fairly quickly.
