Hydration Bag Replacement Bladder

The OGIO Hydration Bag Replacement Bladder is a reusable hydration reservoir that brings a tired hydration pack back to life, or gives a plain backpack a drinking system. It comes in 2 L and 3 L, opens along the top with a slide-lock closure wide enough for a handful of ice, and feeds a TPU drink tube with an angled bite valve.

Who it's for

Riders and walkers whose old bladder has sprung a leak, gone cloudy or started to taste of last summer's sports drink. OGIO designed it for dirt bike and outdoor use, so it is at home in a moto hydration pack on a trail ride through the Glass House Mountains state forests or in a daypack on a long walk. The 2 L suits shorter rides and half-day walks; the 3 L is for full days when water stops are far apart.

Capacity and fit

• 2L: 2.0 L capacity
• 3L: 3.0 L capacity

Volume markings printed on the front show how much is left at a glance and make it easy to mix electrolytes at the right strength. Before you buy, check that your pack's sleeve takes a bladder of the size you are choosing: a 3 L reservoir needs a pack built for one.

Drinking and refilling

The slide-lock closure runs across the top of the bladder, so filling it is a matter of opening it wide under a tap, dropping in ice, then sliding the lock across to seal it. The angled easy-flow bite valve delivers a constant, steady flow, and the TPU tube carries no plastic taste or smell into your water.

Cleaning and mould

The same wide opening is what makes this bladder easy to keep clean. You can get a hand or a brush right inside, and prop it open to dry completely after each ride. The polyurethane film is BPA-free, and the seams and the tube exit port are radio-frequency welded for a strong bond at every join.
