Summit Vannflaske med sugerørlokk

It’s been hours since I filled this with ice water and it’s still ice cold, the vacuum insulation really works. The straw lid seals tight even when tossed in my bag, which is a relief.

Took this on a six-hour road trip and the ice was still clinking around when I got home, so the vacuum insulation does exactly what it promises. The straw lid is genuinely leak-proof too, I tossed it in my bag sideways without a single drop escaping.

The straw lid really is leak-proof, which gives me peace of mind tossing it in my bag. It keeps water cold for hours, though I wish the mouthpiece was a bit softer to sip from.
