Keep Your Drink Cooler, Longer—Stylishly.

Our sleeves are powered by the same high-performance material used in wetsuits—4mm thick Neoprene! This magic rubbery stuff has a closed-cell structure that slows down heat transfer, meaning your drink stays icy-cold (or piping hot) way longer than with those flimsy alternatives. Add in a soft fabric shell, and you’ve got top-tier insulation that blows ordinary sleeves out of the water.

Meet the JavaSok—Your Cup’s New Best Friend.

Perfectly tailored to fit popular cup sizes, the JavaSok hugs your drink like it was made for it (because it was). The flexible neoprene stretches just right, giving you a snug fit that keeps things cool without the sweat—literally. Want to be sure yours will fit? Check out our handy Will It Fit guide!

Say goodbye to scorched fingers and sweaty palms. Our exclusive ThermoFoil™ Protective Barrier adds a powerful layer of insulation and keeps your hands comfy—whether you're sipping something frosty or toasty.

And thanks to our clever closed-bottom design, you can officially forget about messy drips or mystery puddles. You're welcome.

You’ll find ThermoFoil™ tech keeping things cool (or hot!) in all your favorites—CanSok, HotSok, PintSok, IceCreamSok, and the LunchTote.
