Trek Pivot Interchangeable Straw/Chug Lid

I love that I can switch between straw and chug without changing the whole lid—the swap takes just a second. It seals tight enough that my drink hasn't leaked once, even when I toss it in my bag.

The chug piece snaps in so securely it feels like one solid lid, yet popping it out for the straw takes zero effort even with wet hands. I’ve swapped them mid-hike without spilling a drop.

The ability to swap between straw and chug modes on the same lid is brilliant—I’ve been using the chug piece for my morning coffee and the straw for water later. It seals tight without any leaks in my bag, and the whole thing feels sturdy.
