Summit vattenflaska med sugrörslock

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 seals much better than I expected, so tossing it in my bag sideways hasn’t caused any leaks yet. Ice water stayed cold through a full afternoon at my desk, which is exactly what I wanted.
