Fully packed - 12” x 6” x 14.” It filled the main compartment of my Patagonia lightweight tote pack. I crammed 6 days worth of casual, polyester roll-up clothes in it.
Cube abuse. I don’t know how long the zipper can survive such tight packing. I had just enough space left in the main compartment for a zip-up fleece vest. (A large man will not be able to pack as many items as I did.)
This is a good cube for “under-seat” bag packing.
