Titan Aurora Flaskekork

Fits perfectly on the bottle, and the threading feels exactly like the original so there’s no wobble when I screw it on. The titanium finish matches the rest of the bottle, which I appreciate since I’m picky about little details.

I was worried the cap might not seal as well as the original, but it fits perfectly snug and the threading is just as precise. No leaks so far after a week of daily use.

The replacement cap clicks on with that same reassuring tightness as the original, so I don't worry about leaks when the bottle's in my bag. It's clearly machined to the same spec, and the finish matches perfectly.
