Review on Replace Your Nalgene On The Fly Water Bottle Cap With BPA-Free Option by Ronnie Polk

I've long been searching for a convenient water bottle that can be opened and closed with one hand, can be securely locked and has a good water flow. This water bottle(lid) has it all. It fits on the 24 oz or quart size Nalgenes. The button is easy to press and the lid easily flips over to take a swig, and is easily closed by the same hand without repositioning. The metal bar can be simply be locked in place to guarantee that it doesn't come open in your bag. The only other bottles as easy to drink out of are what I call the 'adult sippy cups' with the straws in place for sucking out the water, but the flow rate on the Nalgene OTF is much better -- when you're out of breath and in the heat, you dont want to sip up water a couple drops at a time: you want to gulp it down.I have purchased three of these lids/bottles now including NALGENE 32 oz. Wide Mouth Water Bottle Glow Green 341816 ONESIZE and Nalgene OTF Clear, w/ Green Cap (5565-4024) Note that it if you purchase this lid directly with a bottle, the label on the bottle will be accented with the same color as the lid.
