It hydrates and it massages. The MOBOT bottle, as spotted by Outside magazine, is being billed as “the world’s first and only foam roller water bottle,” and many outdoor and adventure enthusiasts swear by it.

The stainless steel bottle is wrapped in non-toxic EVA (ethylene-vinyl acetate) foam, which can be rolled along your calves, hamstrings, glutes, or arms to soothe sore muscles and relieve joint paint. It was designed with athletes in mind, but we could see it being used by stressed-out office workers with stiff muscles who could benefit from a little self-care. Plus, the lightweight bottle is great for keeping your beverage cold all day, whether you’re at work, at an amusement park, or at the beach. A top loop allows it to be hooked onto a backpack or beach bag.

The bottle is available in three sizes: the 40-ounce “Big Bertha,” the 18-ounce “Firecracker,” and the 27-ounce “Grace.” There’s a range of colors and patterns to choose from, including neon-colored camouflage for those moments when you can’t decide whether you want to stand out or blend in.

You can order it on Amazon, but some styles have already sold out. Check out MOBOT's video below to see different ways of using the bottle.
