サミット ストローリッド付きウォーターボトル

Left it in the car on a 90-degree morning and the water was still icy cold six hours later, which honestly surprised me. The straw lid clicks shut tight enough that I tossed it in my work bag without a second thought.

The straw lid seals perfectly even when tossed sideways in my bag, and the vacuum insulation kept my water ice-cold through a full afternoon of yard work.

Took this on a hot hike yesterday and the water was still ice-cold five hours later. The straw lid seals tight when closed, so not a single drop leaked in my bag.
