ピーク 20オンス 二重壁断熱プラスチックタンブラー

I wasn’t sure how much double-wall plastic would actually help, but this thing doesn’t sweat even after sitting in the sun for an hour. The soft boot on the bottom is a nice touch too—no more water rings on my desk, and it feels sturdy on both hands.

I bought this for my nightstand so I don't have to worry about condensation rings on my wood table, and the soft boot really does the trick — no sweat at all even after hours. The double-wall plastic keeps my iced tea cold till morning, which is a nice bonus.

Ice water stayed cold for my whole shift and the outside stayed completely dry, which is exactly what I needed. The soft boot on the bottom also keeps it from sliding off my desk, so it’s been a solid everyday tumbler.
