The ZÜCA Sport MESH insert bag fits neatly inside our Sport frames. The inserts have a semi-rigid floor and are almost 18" tall on the inside of the main compartment, giving you tons of space to store your most important stuff – wet sports gear, your favorite dog or cat (15 lbs. or less) – you name it, the ZÜCA can take it. Plus there is a clip for your pet's collar and the mesh provides ample ventilation. Well, whatever ZÜCA Sport MESH insert you choose, you’ll not only make your life a little easier, but you’ll express who you are at the same time (well, this week, anyway).
