A must-have two-sided packing cube, the Pack-It™ Isolate Clean/Dirty Cube is built with some extra-awesome functionality. You see, one side is breathable and the other is a bit more secured to hold in (or keep out) moisture or odors. Powered by Protx2® antimicrobial treatment, Isolate Clean/Dirty Cubes keep stinky clothes contained, so you can travel with peace of mind.
