“I really like the pull up cap, have several & they are easy to keep clean & does not leak. The bright color is fun & this coordinates with my starfish stickers.”
“Bought the olive green pull up cap for my bottle and it’s a perfect match! I like that it easily comes apart for cleaning, but my experience has not shown that it’s fully leakproof- I’ve had numerous minor small leaks with this cap. Also, the taste of the micro drinks seems different and less intense when aerated by the sport cap, and I’ve found I prefer to drink from the bottle lip and use a solid cap.”
“I purchased the pink and green caps to go with the two bottles I have, and they work great! Very good flow through the cap with no leaking. Only complaint is that the loop on the cap isn't hinged, but that's not really an inconvenience for me.”
