Summit Vandflaske med sugerørslåg

I’ve been using this bottle during long hikes, and the vacuum insulation keeps my water chilly even after a full afternoon in the sun. The straw lid seals tightly when flipped down, so I can toss it in my bag without worrying about leaks.

Ice water stayed properly cold through a full afternoon on the trail, and the straw lid really is leak-proof when you snap it shut. I tossed it in my bag sideways without a drop. The double-wall insulation does exactly what it promises.

The straw lid’s close position really does seal tight—I tossed it in my work bag with no leaks at all. Cold stayed cold for a few hours, though I was hoping it would last a bit longer into the afternoon.
