Summit Waterfles met Rietjesdeksel

Easy to sip from the straw lid without worrying about spills, and the vacuum insulation really works—my water stayed icy cold during a long hike. I like that the close mechanism is simple and actually leak-proof when I toss it in my bag.

The straw lid actually seals tight enough that I tossed it in my bag sideways without a drop escaping, which is a huge win for me. I also love that the double-walled insulation keeps my water icy cold for hours even in a hot car, so it’s become my daily driver.

The straw lid locks shut with a firm click, so tossing it in my bag hasn’t caused a single leak yet. Only downside is the insulation keeps things cold a bit too well—my iced tea stayed icy for hours, which isn’t a complaint, just a heads-up.
