The Sweet Spot Between Slim and Substantial

When 22 ounces isn't quite enough, but 40 feels like overkill, 30-oz. tumblers hit the perfect middle ground. They hold plenty of hydration without weighing you down, and they move easily between work and weekend plans. Whether you're sipping morning coffee or ice-cold water, this size gives you all-day versatility without the bulk. With a sleek silhouette and a grippable exterior, it's a no-brainer for anyone who's always on the go. Looking for a bottle that keeps up day after day? This is it.

Smartly Designed and Ready for Anything

Our 30-oz. tumbler is one of those "where has this been all my life?" kinds of products. Big enough to keep you hydrated through meetings and weekend errands, but not so oversized that it hogs your cup holder. It's made from powder-coated stainless steel, vacuum-insulated, and topped with a lid that stays put. The wide mouth makes refills quick, and it's totally fine to toss it in the top rack of your dishwasher when the day's done. Sleek and sturdy, this tumbler makes every day easier.

This isn't just a tumbler. It's a statement. Every 30-oz. tumbler you order from WATR helps fund clean water projects through our nonprofit partner, Drink Local Drink Tap.

With every sip, you join a ripple effect that reaches far beyond your desk or car cup holder. And for organizations looking to lead with values, this is an easy (and good-looking) way to start.
