One size, multiple benefits: The three medium-sized cubes in the Pack-ItA(R) Mixed Packing Cube Set use a variety of 100% recycled fabrics to serve an array of packing needs. The heavyweight Gear Cube contains sharp or rough-sided tools and offers weather-resistant protection. The see-through mesh of the Reveal Cube provides a glimpse of your next outfit, and when weight matters, the lightweight Isolate Cube organizes contents without adding bulk.
