Osprey hydraulics reservoir dryer

I designed this hook and oval “thing” to thoroughly dry out your Osprey hydraulics or similar hydration reservoir. To use, blow into the bite valve to clear out the hose and then dump the remaining water out of the reservoir. Insert the oval to hold open the fill flap and hang it upside down overnight from the hook attached to the base of the hose. I have reservoirs that are 10 years old that I dry out this way after nearly every use and I've never had even a hint of mold. Take care of your gear and it will take care of you.
