So, the genius of this fantastic wash bag is that the fabric used on each side is stretchy. This means you can pack a little for short trips (airbnb or hotel where you won't need your own toiletries) or REALLY load it up for longer trips, or for use between an exercise session and work (where you need ALL your stuff). The large pocket easily fits 3 large size GoToobs AND a roll-on deodorant bottle. In the small compartment, I keep a toothbrush, small toothpaste container,mini hair serum, perfume diffuser and a folding travel brush. The detachable section easily fits my basic make up set (liquid foundation, concealer, pressed powder, blush, single eyeshadow pot, eyeliner, brow pencil an a few brushes). Even when filled to the brim, this can still be folded in to the body of the bag and zipped, due to the stretchy outer fabric. Given how much it fits, it's smaller than you'd think too. The stretch fabric on the external pockets is also semi opaque, and allows objects inside to dry without needing to remember to air them out. It can also be used as an awesome first aid kit. I bought a second one I had a kid to transform any bag into a nappy bag. For some reason, I put a LOT of thought into my original purchase of this bag (I guess I had been burned by a few rubbish toiletry/make up bags that were either too small, too bulky.. or too ugly), and I'm so glad I went with this one. I have since gifted this wash bag to several to friends, and it's become an object I use every day (taking make up to work and gym), not just when traveling.
