Summit Vandflaske med sugerør

I was a bit skeptical about the straw lid being truly leak-proof, but it held up perfectly in my work bag. The double-wall insulation keeps my water cold for my entire morning hike, which is exactly what I needed.

Took this on a long hike and the water stayed ice-cold for nearly five hours, which shocked me. The straw lid locks tight enough that I tossed it in my bag without a single leak. This is the bottle I've been looking for.

The vacuum insulation actually keeps my water cold for several hours during my hikes, which is a big plus. My only small gripe is the straw requires a bit of a suck to get the flow started, but it’s still a solid bottle.
