If you buy this bottle, just know the cap will break into 2 pieces. 1 will be the metal, screw-in plug that will become your functioning cap. It will have a razor-sharp edge on the top...enjoy that!
Backcountry acknowledges the issue but does not carry the plastic 1-piece top that KK makes. Once you replace the cap, with that one strait from KK, the bottle will last forever and taste great!
