Summit vattenflaska med sugrörslock

Left it in the car during a scorching afternoon and the water was still ice-cold when I got back hours later. The straw lid’s close function is genuinely leak-proof too—tossed it in my work bag with no drama.

Took this on a long hike and the double-walled insulation kept my water ice-cold for hours, even in the sun. The straw lid is completely leak-proof when closed, which saved my bag from getting soaked. Exactly what I needed for all-day adventures.

The straw lid’s close function actually seals tight—I tossed it in my work bag with coffee and not a drop leaked. Ice stayed solid for a solid six hours, though I wish the mouthpiece were a bit wider for quicker sips.
