Hydration bladders make hands-free drinking easy — clip the drinking tube to your shoulder strap, bite the valve, and sip without breaking stride. Our water bladders collection features reservoir systems from 1.5 to 3 litres suited to day packs and larger tramping packs. Wide-opening tops make filling and cleaning straightforward, while bite valves and flow regulators are designed for easy use on the move. Insulated drinking tubes help prevent the water getting too warm in summer and too cold in winter conditions. Water bladders NZ trampers and trail runners trust are made from BPA-free materials and designed to fit the majority of compatible hydration packs. A clean, convenient way to stay hydrated on the trail.
