Genuine HydroFlask custom parts! Small Flex Boot Color: Cascade For 12-24oz bottles. *Please note: Not compatible with 32oz bottles.* Attaches to the bottom of your bottle to protect it from dents, scratches, and dirt if dropped. You can also add your favorite color to express your individuality. It's also fun to see new colors released every year! It's also exciting that older colors become unavailable when new ones are released! I've noticed some sellers copying and pasting descriptions or using screenshots... It's as if they're using someone else's page. Please be careful not to be deceived by similar products or other people. m(_ _)m
