It does exactly what it says it will do. Extremely high quality. Just feels nice. Maintains its shape but can also compress if not packed to the max. I use it for gym accessories including some items which get sweaty. The mesh allows everything to breath and I don’t have to worry about musky smell which would often develop in closed fabric bags. It would be nice to have a couple flat organizer pockets on the inside of each compartment to keep smaller items. Probably could have gotten the small but also now have an excuse to buy another. If there was another small tab, like what the triangle carabiner attaches to, on the opposite side of the bag it could be hung inside the top of a brain bag using a gatekeeper clip. At the same time, being able to easily pull this out of my bag and put into others, or just carry it around, is a great feature. I love Tom Bihn and all the amazing solutions they offer. No shortage of creativity. I would love a version that is mesh on one side and a slightly slimmer full fabric compartment on the other side (a hybrid of the Snake Charmer and Side Effect)
