The Thule® Compression Packing Cube Set is constructed of bluesign® approved exterior polyester and 100D ripstop nylon material that is water-resistant. The set includes one small and one medium compression cube. The small size is ideal for socks, underwear, and shirts, while the medium size is great for jeans, leggings, and shirts. A durable compression zipper eliminates excess air between clothes to maximize packing space. The semi-transparent fabric allows you to see what is inside while keeping belongings discreet. The cube opens wide for easy packing, and a webbing handle allows you to easily grab and hang the cube while traveling. Made with premium YKK zippers for added durability. Compressed dimensions are 14'' H x 10'' W x 1.25'' D. The small cube's dimensions are 10"H x 7"W x 4"D when expanded and 10"H x 7"W x 1.25"D when compressed.
