Nalgene Cantene 1.4 Litre Collapsible Water Bottle
Carry water, not extra weight or bulk. When this soft-sided bottle’s empty, it packs down flat in your bag. The wide mouth opening fits most water filters and makes it easy to toss in ice to keep your liquids chilled. Bring extra water to refill a hydration system, or take it travelling – just empty it before pre-flight checks at the airport and then refill before take-off.
