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

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.

This cup is a great size. My drinks last my entire shift. The cup has a rubber grip pad made on the bottom to prevent it from slipping on any surface. It’s BPA Free and has a slide to open lid. This cup keeps cold drinks cold and hot drinks warm for hours.
