We know it's still summer, but Nalgene have turned to autumn for inspiration for their latest Tritan bottles. Available in seven new colours - olive, aubergine, melonball, cerulean, clementine, pomegranate and woodsman - they're accompanied by Nalgene's usual selection of funky lids.  If you're a long-standing Nalgene fan, rest assured that it's only the colours that are 'new' - each Tritan is still manufactured to the same medical-grade quality that's made this brand a legend in the hydration market.   Now BPA-free, Nalgene's Tritans remain super-durable and are the perfect choice for your own re-usable 'Bottle for Life'.
