獨角獸魔法運動水壺

Left it in my car all day in July heat and the water was still cold when I got back. The 25-hour claim seemed like marketing talk until I actually tested it.

Took this to the gym and the water was still cold when I got home five hours later, which honestly surprised me. The wide mouth makes it easy to add ice cubes and actually get them in there.

Filled it with ice water before a morning hike and there were still cubes rattling around the next afternoon, which honestly surprised me. The 25-hour cold claim holds up better than I expected.
