Review on humangear capCAP+: The Ultimate Blue Bottle Cap for All Your Hydration Needs by Robert Arneson

I have used closures on Nalgene and other bottles for years and have always loved them. They are durable, dishwasher safe and will not leak. I ordered a Cap + Cap for the first time and was a bit disappointed. It still doesn't leak and is still easy to clean, but something about the new design means that the top cap (the part that screws into the mouthpiece) doesn't turn independently of the bottom cap (the part that goes in the mouthpiece is screwed) rotates the bottle). easy. This makes it difficult to open up easily, especially when you're active. I ended up putting it aside and using the original CapCap instead.
