Ella V. ★★★★★

Filled my wide-mouth bottle with hot tea before a 20-degree overnight and it was still warm at sunrise. The insulation actually works, and it slid into my pack's side pocket without any hassle.

James ★★★★★

The threads held up fine after a full day below freezing, and my tea was still steaming when I stopped for lunch. Wide-mouth Nalgene fit in without any struggle, which is exactly what I needed.

James ★★★★★

Took this on a week-long trip where the thermometer hit -15°F at night, and my hot tea was still steaming by morning. The fit on my wide-mouth Nalgene is snug enough that I never worried about spills in my pack.
