GeoPress® Replacement Drink-Thru Cap

The threads match perfectly and it screws on tight, no leaking so far. It’s a solid, direct replacement that fits just like the original one did.

I was skeptical at first, but the threads are precisely machined and seal perfectly without any leaks. The cap feels sturdier than the original one that came with the bottle.

The replacement cap snapped on perfectly and the bite valve still has that satisfying give when you drink. Saves me from having to buy a whole new bottle.
