Eagle Creek's Pack-It Specter On Board is a large padded wash bag with main compartment plus lots of smaller pouches and zipped pockets. Ideal for other stuff as well.

An ultra lightweight toiletry kit with multiple organizer pockets and a swivel hook for easy hanging and access. Made in durable, translucent, silnylon ripstop.
Eagle Creek's Pack-It Specter 'On Board' is a padded washbag, and as such its very good - quite large, it will swallow a lot of kit with its large main compartment and lost of small pockets, zipped and otherwise. I found it really useful for electrical items - chargers, adaptors, portable mouse, camera and accessories, plus a host of smaller stuff all fitted into the 'On Board' easily and kept this stuff protected and well organised.
If you're using it as a washbag (as intended) you may fond the large hook useful for campsites where shelves in the washrooms are limited.
