Summit Vandflaske med sugerør

The straw lid really is leak-proof, I tossed it in my bag without a second thought and not a drop escaped. My water stayed ice-cold through a whole afternoon of errands in the heat.

The insulation works perfectly—my morning iced coffee was still cold after a full workday. And I love that the straw lid snaps shut securely without any leaks in my bag.

I’ve been using this bottle on my commute all week and the vacuum insulation is no joke—my water stayed ice cold through a full workday, even sitting in a hot car. The straw lid clicks shut tight, so zero leaks in my bag, which honestly was my biggest worry before buying.
