The 6 best water bottles we tested in 2021

The best water bottle overall


The Hydro Flask Wide Mouth water bottle is durable, keeps water ice cold for hours on end, looks cool, and is easy to use.

Pros: Very durable, great at keeping drinks cold or hot, easy to use, compatible with three kinds of lids, comes in high-capacity options

Cons: Heavy, expensive, flip top may leak, not dishwasher-safe

Hydro Flask is a great choice if you hate gulping warm water in the summer. It also offers some much-appreciated versatility, with a wide opening that fits three lids depending on your needs: A flip lid with a loop, a flex cap with an even larger loop (included), and a straw lid for more convenient sipping. We like having the option to switch out lids, and the wide mouth also makes it easy to load this bottle up with ice. You can choose between 18-, 32 -, 40- and 64-ounce capacities and a number of fun colors.

During Outdoor Gear Lab’s testing, ice resisted melting for nearly a full 24 hours, and water was ice cold for more than a full day. The insulated stainless steel also keeps drinks warm for several hours, so Hydro Flask can pull double-duty as a travel mug for coffee and tea.

This thing is seriously rugged, too. Like all stainless-steel water bottles, it can dent when dropped, but in Outside’s tests, it managed to survive being pelted with large rocks and getting backed over by a Toyota Camry and a Chevy Silverado. After all that punishment, it sustained a quarter-inch dent and one small scratch. It also has a loop on the lid that makes it easy to carry one-handed.

Insider Reviews senior reporter Owen Burke calls Hydro Flask water bottles “lightweight and nearly indestructible” (he tested the 24-ounce version). But he found the silicone loop on the lid to be “not the most durable thing in the world, and it will eventually break.” Nearly every member on the Insider Reviews team uses a Hydro Flask. You can read about their experiences on why they like the company’s products.

It’s heavier than other bottles (the 18-ounce version weighs in at 11.6 ounces, the 32-ounce closes in on 1 pound) so serious hikers looking to save on weight might want to consider lighter options.

The flip-top is not leak-proof, so consider sticking with the flex cap if you want to toss your bottle in a bag without worrying. A few also complain of a slight metallic taste. Finally, this bottle is hand-wash only – steer clear if you live and die by the dishwasher. — Saundra Latham
