Product Information

Though it’s not dishwasher safe, all you need to do is separate the cap and collar from the bottle and get in there with some warm water and soap (or baking soda if you need to be more thorough). The handle doesn’t have rivets and only snaps into place, but it doesn’t detach from the cap. Chilly’s doesn’t recommend trying to do so because it could cause permanent damage. However, when they say not to overtighten the collar or cap, they mean it. This could be because overtightening may strip the screw top, but we think it has more to do with how the collar and cap interact. Chilly’s Series 2 Water Bottle | The collar sometimes comes along for the ride. Its antimicrobial collar does have a small few gouges on it, almost like the plastic got caught on something and scraped off. This could be from accidental tooth bumps, but it’s also possible that it got damaged during cleaning. We can’t vouch for whether it affects the antimicrobial performance, though it doesn’t impact the cap’s seal.

Separately, they tested for comfort, design, and ease of use. If a mug claimed to be dishwasher safe, they ran it through multiple cycles and noted any changes in quality.

Features & Usage

To put these market-leading travel mugs to the test, our GHI experts aimed to simulate different aspects of everyday usage in the lab. They tested leakproof claims by filling each mug to its maximum level, before tipping it on its side for 20 minutes. For accuracy, they weighed the mug before and after to measure any weight loss from spillage. It’s worth noting that there’s no option to close off the opening on this cup, so if it toppled on its side it would obviously spill out through the sipping hole. Look for a leakproof lid, especially if you’ll be carrying the mug in a bag. Every reusable coffee cup on our list passed our leak tests with flying colours, so you can buy with confidence below. Consider how long the mug claims to keep drinks warm or cool for, too, so that you don’t arrive at your destination with a lukewarm beverage. We opted for a single-color look with the Maple colorway. We noticed that the collar and loop are a slightly different shade compared to the bottle, though it’s not surprising as they’re different materials. The bottle itself is stainless steel with a matte exterior, while the collar is plastic infused with an antimicrobial additive called BioCote®. The handle is a similar soft plastic to the collar but is not antimicrobial. Chilly’s Series 2 Water Bottle | The antimicrobial collar is super comfortable to drink from.

At the time of writing, there are ten colorways, all with a sleek matte finish. You can choose a separate color for each part—except for the cap, which is always stainless steel. Whether you want to rep your favorite sports team or create an aesthetically pleasing combination of colors, the world is your oyster. Well, at least three parts of the water bottle world.

Materials & Aesthetic

That’s a lot of numbers to look at, we know. Essentially, our test shows that the Original Chilly’s Bottle kept water 2.6°F (1.6°C) colder than the Series 2 on average. However, the Series 2 has updated features like the antimicrobial collar, carry handle, and silicone bottom, potentially making this slight temperature difference a non-issue depending on your preferences. Chilly’s Series 2 Water Bottle | This water bottle is not friends with cement.
