Best High-Capacity Bottle
Hydro Flask 32-Ounce Wide Mouth Bottle
The Hydro Flask 32-ounce Wide Mouth bottle with Flex Cap is a stellar option both for in your pack and toting around town. The cap has a handy carry handle, but you can also reliably pick up and set down the body without slippage thanks to the textured powder coat on the 18/8 pro-grade stainless steel, which worked well even with numb hands on a frigid day in the Colorado mountains. The bottle has double-wall vacuum insulation, and reliably kept tea warm on cool days (and conversely, tap water cool on hot days). Weighing 15.5 ounces (empty), the 32-ounce Wide Mouth is no featherweight, but in return you get a durable, long-lasting container with superb insulation properties. If you prefer a more streamlined option that has a smaller mouth and fits in cupholders better, the Hydro Flask Standard Mouth water bottle has you covered. Buy this here.
Best Bottle With a C
Klean Kanteen TKPro Stainless Steel Double Wall Insulated Water Bottle
Kleen Kanteen has long been a big player in metal bottles, and their 0.5-liter TKPro Stainless Steel Double Wall Insulated Water Bottle with Stainless Steel Cup lives up to the brand’s high standards. This is a great bottle for trekking—the integrated cup, which doubles as the bottle’s lid, makes it a snap to pour out a quick cup of tea, then seal things back up and keep motoring down the trail. The food-grade 18/8 stainless steel is electro-polished on the inside of the bottle, while silicon gaskets (no BPA or phthalates) help with sealing: Your drinks pour out with no residual aftertaste, and hot drinks stay warm up to 20 hours, and cool drinks cool up to 75—great for hot climates. Meanwhile, a powder coating makes the bottle very grippable, even with clammy or chilly hands. Buy this here!
Easiest to Operate Single-Handedly
Contigo AUTOSEAL Chill Vacuum-Insulated bottle
Contigo hits a sweet spot with their 24-ounce AUTOSEAL Chill Vacuum-Insulated bottle, which marries a sleek stainless-steel body with the plastic, single-hand-operable button-activated AUTOSEAL top, which does a great job of eliminating spillage if you’re sipping on the go. The bottle has double-walled vacuum insulation and keeps drinks chilled for up to 28 hours. If one-handed utility is important to you—perhaps you like to carry your bottle while hiking or have it easily accessible in a mesh pocket on your pack—then consider the Contigo. There’s also a handy mini-handle/U-shaped ring on the top lid for easy one- or two-finger carry. Buy this here.
