BUILT Torrent 30 oz Double-Wall Insulated Stainless Steel Tumbler Water Bottle, Teal

Even in hot and humid weathers, the tumbler is excellent at retaining cold beverage temperatures. Took this with me on a trip to Singapore, and used it daily as a beverage holder in the flat I stayed in - and I’m SO incredibly glad I did. Nothing stays cold here in 100 degrees and 90% humidity, plus all the drinks sweat like crazy. So I used this for iced drinks or ice water. It stays cold for 10-12 hours and never sweats because it’s double insulated. When I returned from my trip and used this back at home where temperatures aren’t crazy hot (so back to 75F, 50% humidity), the ice in this tumbler sometimes stays in ice form for 12 hours - which is perfect for me, as someone who loves drinking cold water all the time. I don’t necessarily need this to stay cold for 24 hours, as it advertises. So staying cold overnight (as water by my nightstand) or all day when I’m out and about in my car is already more than enough. Plus, I love that it fits in my car’s cup holder. This is an enormous 30oz, but it’s easy to hold, and the lid makes a satisfying click when I slide the mouth piece open and shut. Note: it is not leak proof, in case anyone was wondering. I’ve never used it for hot beverages.

So far I'm very pleased with my Built Torrent Tumbler. The lavender color is amazing! The 30 oz size is perfect. I love that I can fill it to the top with ice and also pour a full can of pop in it. This is a double wall stainless steel. It actually did keep my coffee hot for well over the 16 hours. I mostly drink cold stuff. So I fill this to the top with ice, then a full can of pop, and 24 hours later the ice still isn't completely gone. I'm sure the cold performance will be even better once our 90 degree days are over. The lid slides open to either drink or add a straw. The tumbler stands 9 inches tall and a straw isn't included.
