I could not post a response to the travel pouches thread - post button kept spinning. So I am creating a new thread...

Here are some of the pouches that I use:

Evergoods Civic Access Pouch 1L for computer cords, USB-c hub, charger, adapters.

Peak Designs medium packing cube for clothes (up to 2-4 days worth, minus shoes)

Gravel minimal toiletry bag for indefinite supply of toiletry items.

Maxpedition pouch I use pouch this as a dump pocket that I attach to inside of backpacks with attachment points (e.g. Molle webbing on GoRuck bags, Evergoods, etc.). I like this one because it has lots of pockets and very little structure. Can also use unattached to organize loose, small items.
