Celebs love them. Social influencers love them. Regular people love them. High-end water bottles are having a major social moment, and its not just because brands like Swell, Hydroflask, bkr and Bobble have turned a purely functional item into a desirable fashion accessory. These bottles are helping to save the planet and millennials, in particular, cant get enough.

At first glance, these aesthetically pleasing bottles might seem a bit excessive. Americans access to water is very inexpensive, if not free, while these decorative bottles will typically set you back between $30 and $50, even upwards of $100 depending on the size, availability and number of rhinestones.

Despite the price, business is booming. The global market for reusable water bottles, plain and fancy, is predicted to be worth $10 billion by 2024 .

This is partially thanks to celebrities like Jennifer Garner, Reese Witherspoon, Emily Ratajkowski and Jenna Dewan who have been photographed with reusable bottles in the same way they were once photographed wearing Juicy Couture tracksuits and Dior Glossy sunglasses.

Bottles worth a second look have also become extremely popular with social media influencers. Whether those folks are working out, traveling, running errands or simply displaying makeup on a marble countertop, the bottles make an appearance.
