Nalgene Outdoors is a hydration company that manufactures a wide range of virtually indestructible water bottles. Nalgene was founded under the name Nalge in the 1940s by a scientist who created the first plastic pipette jars. By the 60s, his fellow lab scientists were taking Nalge products hiking because they were leakproof and lightweight. During the 1970s, the Carry In/Carry Out camping philosophy was popularised. In response, Nalge created Nalgene Outdoors and made BPA-free, reusable water bottles and containers available to the public.
