Polarpak MoFlow Shower Attachment
Here's what other sites are saying:
Can't find a tree branch from which to hang your gravity-dependent backcountry shower? Bummer. Shoulda brought the Polarpak MoFlow Shower Attachment System. If you had, you could pair the shower attachment with your MoFlow Hydration System reservoir (sold separately) and take a shower just about anywhere. The MoFlow reservoir features an air pump, which pushes the water out instead of your having to suck it out. Attach the shower head, and the reservoir's air pump gives you enough pressure that you could lie the bladder on the ground and still be able to hose yourself down. Brilliant, no?
