Trek 樞軸不倒杯

Didn't think I'd care about the two lid pieces but the chug top has basically replaced my straw habit. No leaks in my bag so far, even tossed sideways in a tote.

Swapping the lid between straw and chug modes is incredibly handy, and it hasn’t leaked once in my bag. The leakproof design really delivers.

I take this to the gym every morning and it hasn't leaked once, even tossed sideways in my bag. Swapping from the straw to the chug lid takes like five seconds, which is perfect when I'm switching between iced coffee and water.
