This tumbler will keep drinks hot or cold for hours on end, is dishwasher-safe and, yes, will fit into your car’s cupholder.

Built from stainless steel with double-wall insulation, these cups keep drinks hot or cold for a long, long time; some say hours, others say practically all-day. It also features flexible straw, instead of those harsh plastic or metal ones, a splash-resistant lid that features a tight closure to prevent leaks and comes in plenty of colors.

Hydro Flask has some major pros over its competitors, according to several reviewers, but if you ask me, the biggest is with keeping it clean. You can stick the cup, straw and lid into the top rack of your dishwasher to clean and sanitize them. Other brands recommend hand washing only to preserve color, but not Hydro Flask! That saves the pain of using bottle brushes.

“It’s worth the hype — I love it,” says a user who grabbed a pink cup. “Perfectly aesthetic, and I appreciate that it’s easy to wash. Keeps my water cold all day. It’s sturdy, the lid quality is great, slides on and off easily while still being nice and snug when on its on. I’ve tipped it over a couple times already and the lid stays put.”

These Hydro Flask tumblers are on sale for a very limited time, so grab one (or two) while you can! And take a look below to see what people are saying about this fan-favorite cup.
