It’s the small details that can really stand out. Great addition to an already great product!!!
I have used this kit for the past couple weeks in the dead of Illinois' summer, and it works great! The spring creates a proper curve to the tube so that water can freely flow into the mouthpiece. I have only one complaint; I had to secure the bottom part of the kink spring to the spout with electrical tape. Before the tape, the spring would tend to ride-up on the tube about mid-shift when it was in my vest carrier at work. Other than that, this kit works great!
