Why these three bladders

A bladder lets you drink without stopping. It also hides how much water you have left, freezes in the hose, and is harder to clean than a bottle. Most of a PCT class still carries bottles. If you want a hose anyway, these three are the ones worth buying.

HydraPak Contour 3L is first: about 5.4 ounces with the tube, a slide-seal top, independent tests still put it on top. Osprey Hydraulics 3L is the Premium Pick — the reservoir that ships in hiking packs, with a handle you can fill at a trough. Platypus Hoser 3L is Best Value: the lightest hose system on this list, a lower price, no extra hardware.
