Osprey Hydraulics 3 Liter Reservoir
This is a replacement 3L reservoir. New Metallocene PE high strength & taste free film (BPA & PVC free). Anti-microbial formula prevents bacteria & mold. Features a new 3/4 quick turn cap and a HydroStatic backer plate for a wider and lower profile.
Many good functions on this bladder, but the way the rubber bits are attached to the plastic bits is untenable. I have seen so many of these bladders tear where the rubber of the bladder attaches to the fill-hole and handle. This bladder promises greatness, but hasn't achieved the durability to yet do so.
