The Cotopaxi Cubo 12L Expandable Packing Cube does the unglamorous work of keeping your stuff from turning into a tangled mess, whether you're stuffing it into a carry-on for three days or a 60-liter pack for three months. Built from 100% recycled mesh that weighs almost nothing, it compresses down to 8L when you need breathing room in your bag or expands to 12L when you're maximizing every cubic inch.
