The pump sits in a bucket, basin, or any open water source and pushes it through a flexible hose to a handheld shower head.
Charges over USB; one charge runs the pump for roughly 45 minutes of use.
Under 500g, so it packs into a side pocket rather than taking up main pack space.
Switches between a full spray and a narrower rinse at the shower head.
Includes: pump unit, hose, shower head, USB charging cable.
