Durable, weatherproof, and exceptionally lightweight, Peak Design Ultralight Packing Cubes guarantee organizational bliss for all the random odds-and-ends you're traveling with, whether you're hitting the backcountry for a week, visiting family for the weekend, or just running through your weekday routine. Based on our full-featured and astronomically popular original Packing Cubes, Ultralight Packing Cubes are stripped down to the essentials: a single volume with a single zip for access. But don't go around calling these cubes simple—thoughtful features are abound. Choose from 2 fabrics: our weatherproof Terra Shell 50D material, and our see-through nylon stretch mesh. Terra Shell cubes have taped seams and weatherproof UltraZips for enhanced water and tear resistance, while the stretch mesh can expand to double the max volume, and is also ideal for things that need to breathe. Turn your cube into an ultralight sling by attaching an adjustable carry strap or PD camera strap (both sold seperately) to the Cord Hook carry loops. Or mount your cube externally on any Peak Design bag via 2 external carry strap pass-throughs—a whole new dimension to modular organization. When not in use, Ultralight Packing Cubes fold totally flat and can be rolled up and cinched with the elastic zip pull cord. Keep a few of them on hand in your pocket or bag—you'll never stop finding uses for them. Designed for use in any suitcase or bag, and sized to fit perfectly in any Peak Design Travel or Outdoor Bag.
