This 18 inch duffel is perfect for any running/racing vacation. We selected this bag because it is just the right size to carry-on and it has enough space to carry everything you'll need on race day. It features an isolated shoe compartment with a mesh side. If you have to put wet shoes in, the mesh will allow them to dry and the compartment lining will keep everything else in your bag dry. It also features a side pocket with two zippered compartments perfect for your travel documents and electronics/accessories.
