We switched to new, larger caps recently that are the same diameter as the bottles. Although the new profile took some getting used to, we feel these are a huge improvement, both aesthetically and especially in terms of how the bottles feel and handle. Some people who have multiple bottles have expressed an interest in replacing the older caps so all the bottles match, or just because the new caps are pretty cool.

For $10 to cover postage, packaging and labor you will receive new, larger caps for every bottle you've purchased through the website. If you need extras to replace bottles acquired via other channels, contact us after purchasing.

12/9 Note: There have been some issues with a few of the new caps. They do relax over time but if you have a tight one please use caution and pull directly upward to remove. Once removed, we fine that simply replacing it and removing it several times is generally enough to ensure smooth operation but we’ll be on the lookout not to send tight ones going forward.
