We’re done with single-use plastic – in fact, we stopped buying bottled water years ago. And thus began the quest for the ultimate water bottle. A quest that went on and on until we discovered Nalgene’s latest line of Sustain bottles. Just as tough and rugged as the iconic originals – famed for their near unbreakable toughness and leakproof design – but now made from 50% waste plastic. In fact, Nalgene are turning flimsy, single-use bottles destined for landfill into high-performance, BPA/BPS-free Tritan Renew resin, allowing us all to swig sustainably. This extra-large 48oz (1.5 litre) wide-mouth version has a huge capacity and is easy to fill with ice cubes, perfect for high intensity activity when you need serious hydration, or for wild camps high in the hills when you might not be close to a water source. This size also comes in a trio of translucent colours, so you can quickly see how much fluid you are consuming or easily mix sports drinks and squash. Of course, many hikers also use their trusty wide-mouth Nalgenes as robust and watertight containers for first aid kits, extra food and so on, particularly on waterborne canoe/kayak trips or multi-day backpacking adventures
