標準口徑彈性吸管蓋

Swapped this onto my bottle for my morning commute and the flexible straw is way easier to sip from while walking than the old flip lid. It's leakproof too, no drips rolling around in my bag.

The straw cap hasn't leaked once in my bag, and the flexible straw is way easier to sip from while driving than tilting the bottle. Swapped it onto my standard mouth bottle in seconds.

Bought this as a spare so I'm not stuck washing a lid every night, and the leakproof seal has held up fine tossed in my bag. The flexible straw is soft enough to sip from without tipping the bottle way up.
