تراك بيفوت كوب

The two lid pieces are genius—I’ve swapped between the straw and chug tops all week without a single spill in my bag. Honestly, the leakproof seal holds up even when I toss it sideways, which is more than I can say for past tumblers.

I wasn't sure about the leakproof claim, but after tossing this in my bag with my laptop, not a single drop escaped. The chug lid is great for quick hydration during hikes.

Swapping between the straw and chug lid pieces is surprisingly easy and makes this perfect for both my morning commute and evening gym bag. The leakproof design gives me total confidence tossing it in my backpack.
