1.2L ステンレス製真空断熱タンブラー（ストロー付き）

I’ve been taking this to the gym and it keeps my water ice-cold for hours even in the car. The straw makes it easy to sip without tilting my head back, and 1.2L means I don’t have to refill mid-workout. Only wish the lid seal was a bit tighter to prevent drips when I shake it.

I was skeptical a tumbler this big could keep drinks cold all day, but the vacuum insulation in this 1200ml beast has held up on two full hikes now. The 30.5cm straw length actually reaches the bottom without me tilting it, which is way better than my old one.

Perfect size for my long shifts — the 1.2L capacity actually gets me through morning to afternoon without a refill. The straw is sturdy and doesn't collapse when I'm drinking something thick like a smoothie.
