Purist’s bottle has a (non-breakable) glass interior that prevents flavors from transferring, so there should be no taste issues like you get with stainless steel or plastic. Hydrapeak will replace any eligible product found to be defective within the scope of normal and appropriate use. Also, though the lid has a ring that you can turn to track your water intake, in practice we’ve found we barely use it. A major reason this bottle outperformed all the other glass options is it’s the only one we found that has a metal-lined cap (rather than some form of plastic). That means using the Union cap, you can fill the bottle to the brim; we did, and that’s when we discovered the bottle can hold up to 21 ounces.

And if you want a 32-ounce bottle, the Takeya Actives properly adapts the proportions of the bottle to accommodate the new capacity: It gets wider as well as taller, so this bottle remains stable when you set it down (though that does mean it’s too broad to fit in a standard cupholder). They can be very easy to knock over, and they don’t stay upright in cup holders because they’re top-heavy. The theory behind using copper in insulation (despite its being an excellent conductor normally) is based on the fact that heat transfers through three forms: solid conduction, gaseous convection, and radiation, Johnson told us. Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions.Our big concern is that this bottle doesn’t roll down particularly small, so it’s up to you to decide whether the space savings are worth it.

Also, some people may not like that a portion of the drinking surface is exposed; the cap threads twist into the bottle rather than over the top and around the lip. The lip of the bottle is on the thick side, so if drinking from a thick-walled bottle would bother you, we’d recommend either the Union or the Scope. Third, the standard lid is watertight but made of plastic, a concern for many people seeking glass bottles. And it passed the leak test, so you don’t have to worry about this bottle’s contents ruining your day, your laptop, or your evening wear.Get this if: You want something that’s easy to sip from while you’re driving, or you want something that encourages you to drink water throughout the day (our unscientific findings have led us to believe that straws make it easier to slurp down water). Our 2016 pick, the Platypus SoftBottle, is watertight but floppy, as all collapsible bag-bottles are. Turning off the personalized advertising setting won’t stop you from seeing Etsy ads, but it may make the ads you see less relevant or more repetitive. We believe good design is human-centered design, and that you should be able to absent-mindedly screw the top back on and trust that the bottle is properly closed.

Our 2017 travel pick, the Platypus Meta, tends to develop a small hole in its bottom, which renders it useless for carrying water. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.It has a few design features that make it more functional than most, including the type of glass it’s made from, as well as an especially useful cap, which is also lined with stainless steel.
