Arctic Ice maintains lower temperatures longer than ice or “blue” ice substitutes. This cooler insert’s reusable active ingredient, PureTemp is a non-toxic, biodegradable phase-change material (PCM) derived from plants. When Arctic Ice approaches its melting point (that’s the phase change) it begins absorbing more heat while stubbornly refusing to warm up. It holds a constant, pre-defined temperature until the entire cooler pack finally thaws. The Alaskan Series freezes at 1 Degree Celsius (33.8 Degrees Fahrenheit) and efficiently keeps food and drinks chilled much longer than the same volume of ice. For optimal performance, freeze Alaskan packs in any household freezer for at least eight hours prior to use.

These suckers are thicker than I expected. I put … These suckers are thicker than I expected. I put some cold cuts in a cooler on top of this one for about five hours and when I got home they meat had started to freeze.
So far outstanding! Very satisfied. Haven’t given the ice and cooler a real hard trial yet. I’ll do that this summer. So far the Arctic Ice has been flawless. Used it on a few runs, the longest being 2 days. Where the “common” blue ice would have adjusted to room temps this has held. It is perfect sized for the cooler I own.
