Cryo Blocks – set of 2

Cryo Blocks are a powerful alternative to ice blocks, enabling your Oyster to reach temperatures as low as 10°F (-12°C). This means you can now store anything from ice cream, food, and medicine at below freezing point for hours. For a portable, non-electric cooler, that’s not just cold—it’s unprecedented. It’s the synergy between the blocks and our DLTA™ technology that makes this possible, transforming the Oyster into something far beyond an ordinary cooler. This isn’t just a product add-on; it’s a full reveal of the Oyster’s hidden capabilities. How to Freeze Cryo Blocks Place the Cryo Blocks in a freezer that maintains a temperature of  0°F (-18°C)* or colder. *standard freezer temperature Allow them to freeze completely. You’ll know they are ready to use when the blocks turn solid white.
