NOT machine washable. I love the idea of a packing cube. Holds what I need to carry to/from the car. Tucks nicely in a waist pack. However, I searched the site for a nylon bag so I could have something durable and e-z to wash.  But, hand wash only, no dryer, and dry away from sunlight. The bag serves me well, but can't justify the price. Maybe consider the small Maxpeditions for a few $ more
