Review on 🚰 BPA-Free Water Bottle Replacement Cap for Nalgene On The Fly by Kev Mills

I bought this cap to convert my non-insulated Blackthorne stainless steel bottles into sports bottles. They don't leak as long as you tighten them tightly. The spout is easy to drink like a sports bottle and the loop is easy to hold when the lid is closed. However, I see the issues others have pointed out. The latch and button feel pretty flimsy. I plan to always close with a metal clip. And the silicone spout seal works I think by pushing the seal apart when closed so I can see how moisture can get in there when the lid is open. I don't mind the ease of use and the price and if it lasts a year I'll be happy. Just don't expect typical Nalgene blast resistance from this cap.
