Nalgene Easy Sipper The first step to recovery is accepting you have a drinking problem. Nalgene bottles are bomb proof, easy to clean, BPA-free and super stylish but if you've bought a Wide Mouth model you already live the struggle of drinking on the move #firstworldproblems #spillsfordays! Enter the easy sipper. Yes it sounds like a no-spills bottle for toddlers but in reality its a neat little insert for your Nalgene allowing you to drink and drive, drink and walk, drink and run. Water, of course. Pops out as easy as it goes in to allow easy cleaning. Comes in 3 colours.
