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 blo...

Worth every penny.
It's always interesting when a new product comes out that rethinks the way products have been made for decades. This is one of those products I'm constantly impressed with: how much I can fit in it while keeping it cold all day and beyond.

It works!
This is not a Yeti. It is not going to fall of the tailgate and be ok. Lets say that first of all. But…. if you want the best cooler on the planet for keeping things cold or frozen(yes, I said frozen) thenn thius is your cooler. I tested it with just the ice packs. I did the ones for cold and and the ones for frozen and it out performed my expectations. With the cols packs it was 38 degrees and with the freeze packs it was 19 degrees. Lid is a different and not used like a normal cooler lid. It can oipen on both sides which means it can fall off if you open it past 90 degrees. But you can still open it from both sides which is awesome. FYI Overall it really works and you dont have to use ice if you have the ice packs so it makes it so much bigger and easier to carry all kind of stuff.

Making New Orleans even COOOOOLER!!!
I was on the fence since day one when Oyster released its first cooler, but when the Oyster Pro landed, I was well intrigued. And then laying eyes on the Cryo blocks, well, being an avid gelato and ice cream afficionado, I thought I had to give these a try. Lo and behold, not only do they work as promised, they keep everything frozen in this Amazon heat we have here in the Big Easy and hold temps for what seems like an eternity!!! GREAT WORK, Oyster!!! The only better invention Oyster could produce would be an even larger Oyster. Maybe call it an Oyster Bed? Ha! Thanks for a PHENOMENAL set of products!!!
