Three in One Organize your gear efficiently with the black Ultralight Mesh Packing Cube Bundle from Peak Design. These lightweight cubes feature a minimalist design and durable zippered closures. Carry loops allow for the attachment of an optional strap, converting the cubes into standalone sling bags. Strap pass-throughs enable seamless connection to other Peak Design bags for hassle-free travel. Additionally, the cubes can fold flat or roll up for convenient storage. Construction Available in three sizes to accommodate various gear, the Peak Design packing cubes come in XX-Small (1L, expands to 3L), X-Small (3L, expands to 8L), and Small (12L, expands to 22L). Constructed with breathable nylon mesh, these cubes allow moisture to escape, preventing mildew—ideal for wet clothes or gear. The stretch material enables expansion to fit bulky or oddly-shaped items, and the see-through fabric allows quick identification of contents. Featuring a durable #5 zip, these cubes are Bluesign approved, Fair Trade Certified, and 100% carbon neutral. They can convert to ultralight sling bags with an optional strap attached to Cord Hook external loops, which also serve as counter pulls for easy opening and closing. Two strap pass-throughs allow external mounting to Peak Design bags. When not in use, the cubes fold flat and roll up for storage, with the elastic zip pull doubling as a cinch ring.
