ロームボトル

Left this in a hot car all afternoon and the water still had ice in it, which honestly surprised me for a bottle this size. The four-way lid is a small thing but pouring without tilting the whole thing awkwardly is nice. No leaks in my bag so far either.

Filled it with ice water before a hike and there was still ice rattling around six hours later. The lid pours from four directions, which sounds gimmicky until you're in the car and don't have to twist the whole thing around.

The 36oz size means I'm not constantly refilling at my desk, and I've left it in a hot car all afternoon with ice still clinking around at 5pm. The lid pours from four directions too, which sounds gimmicky until you're actually trying to fill a mug one-handed.
