"Awesome BUT, if you dont have a deep freezer or some kind of seriously cold freezer, this will not freeze these blocks."
NEW
Cryo Blocks – set of 2
$60.00
Cryo Blocks are a powerful alternative to ice blocks, enabling your Oyster to reach temperatures as low as -12°C (10°F). 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.
Dimensions
A single Cryo Block measures 8" x 8" x 1"(20.5cm x 20.5cm x 2.4cm), weighs around 29oz (830g) and contains around 22 fl oz (650ml) of active ingredients.
HOW TO FREEZE CRYO BLOCKS
- Place the Cryo Blocks in a freezer that maintains a temperature of -18°C (0°F)* or colder. *standard freezer temperature
- Allow them to freeze completely. You’ll know they are ready to use when the blocks turn solid white.
SAY FREEZE!
When we talk about coolers and ice cubes, it’s usually a question of how long until they melt — but with our new Cryo Blocks, your Oyster can actually freeze water, meaning you can now store anything from ice cream, food, medicine etc at below freezing point for hours.
Just to be clear, we're not recommending using the Oyster to make ice cubes, we're simply showcasing how incredibly cold this cooler gets when using these new blocks. How you choose to use them is up to you!

"Best ever made. Please buy more so they have the capital to make a larger taller size"
amazing material
"THese are amazing. NOw can you make a cooler with these a little larger?"
Crying Block will not freeze
"One of the two crypto blocks will not freeze completely. Despite sharing my information with support. They can’t find my order to resolve my situation. But I got this email to review the recent purchase of these blocks. Maybe I can get support through this review."
Cyro Blocks
"Worked poorly. Froze Cyro blocks (4) for 48 hrs -1degree start. Held frozen state (to 5 degrees) only 4 hrs. That's poor performance!"
Cryo blocks
"This is the second set of cryo block I have received and they do not freeze entire in a normal house refrigerator. The blocks were in the freezer for 5 day and never freeze completely. I would not recommend this item."
Cryo Blocks
"Cryo Blocks work great in the Oyster cooler, but just be aware that they do need to be frozen in a deep freezer that is colder than -10 degrees Fahrenheit (-24 degrees Celsius) or they won't freeze solid. Otherwise they are a great product!"
Oyster Before First Use
"I have not used the cooler yet. However, I’ve seen multiple users of it on YouTube. I feel like it will be a game changer, compared to my old cooler, which was bigger, bulkier and much heavier. I am looking for ways to save space in my trunk when I go camping, and the oyster is one of the best ways to save space. I bought multiple ice packs. I have six total. Four are the standard packs, and two are the icier packs. I wanted to experiment with the ice air ones to see when they’re most applicable. Thank you oyster for making such a great product. Thanks, Mark."
Cold but surprisingly limited
"Once frozen they are great. However it the blocks take a long time to freeze in a normal freezer. They melt faster than expected. I end up using my two old blocks and one cryo block for a weekend. Much easier to refreeze the regular blocks if you’re staying in a hotel or Airbnb"
