Abigail A. ★★★★★

I was a little worried the seal wouldn't be as tight as the original, but this replacement cap snaps on securely and doesn’t leak at all on my 3L container.

Ryan B. ★★★★★

The threading lines up perfectly with my 3L container, no leaks even when it's tipped sideways in my pack. I was worried about fit since it doesn't work with the soft flasks, but it screwed on in two seconds. Solid replacement for the price.

Samuel ★★★★★

Finally a cap that actually seals tight on my 4L Seeker without any leaks. The 42mm threading feels sturdy and it clicks on cleanly.
