Socks/Underwear Cube: This cube is divided between two separate compartments, with odor-blocking transparent vinyl to divide your clothes between dirty and clean. It keeps the clean clothes smelling clean, while blocking out the odor from the dirty clothes. No more need to pack a separate dirty clothes bag! Both sides are enclosed with high quality YKK zippers to keep your clothes and underwear secure without the worry of them falling out. A handle at the top makes it convenient for grabbing or holding with one hand. Wolverine mesh fabric covers part of the cube, which will “repair” itself in the event of a small puncture. It fits perfectly as part of the cube system in the Onli Venture Suitcase or Backpack.
