Genuine HydroFlask custom parts! Latest! New color! Small Flex Boot Color name: REEF For 12-24oz bottles. *Please note that it does not fit 32oz bottles.* Attaching it to the bottom of your bottle protects it from dents, scratches, and dirt if dropped. You can also express your individuality by matching it with your favorite color. It's also fun to see new colors released every year! It's also fun that you can't get the previous colors when new ones come out! I've noticed some people copying and pasting the description or taking screenshots of the photos and listing them as if they were on a "mame" page. Please be careful not to be deceived by similar products or other people. m(_ _)m
