サミット ウォーターボトル タンブラー式ストローリッド

The straw lid clicks on so securely that I can toss my bottle into my bag without a single leak. It transforms my usual bottle into something way more sippable for the car, and the straw mechanism is just as smooth as I'd hoped.

I was skeptical at first, but this lid turns my bottle into a proper tumbler and the straw makes sipping way easier during work calls. The seal is tight enough that I can toss it in my bag without a drop leaking.

Swapped the lid on my Summit bottle this morning and it fits perfectly, sealing tight with no drips even when I tipped it sideways in my bag. The straw mechanism is smooth and the sip feels just like my classic tumbler, which is exactly what I wanted.
