Trek Pivot タンブラー

The straw lid snaps on tight, but the chug top is what I keep reaching for since it never leaks in my bag. Ice cubes were still solid after a full afternoon of yard work.

Didn't think I'd care about the interchangeable lid pieces until I actually used both. Chug mode on the way to the gym, straw mode at my desk all afternoon, and neither one has leaked in my bag once.

Took this to the gym and it survived a full tumble in my bag without a single drip, which is more than I can say for my old bottle. The two lid pieces are the real draw though, I keep the straw one in for cold brew days and switch to the chug top for water.
