Topo Designs x MiiR Tampa de Palhinha à Prova de Fugas

Took this on a hike at 9,000 feet and the threaded seal held up perfectly, not a single drop in my pack. The flip-up straw is stiff enough that it doesn't flop around, which I didn't expect to care about until I started using it daily.

I’ve taken this lid on two flights and a rocky trail hike, and not a single drop escaped the threaded seal even when the bottle was jostling sideways in my bag. The straw flips up smoothly with one hand, which makes it perfect for sipping while I’m driving or mid-walk.

Dropped my bottle on a rocky trail and not a single drop escaped through the straw, which honestly surprised me. The threaded seal feels rock-solid and the flip-up mechanism is smooth enough to open one-handed while hiking.
