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!!!

My Oyster is a Pearl!
We love the Oyster and cold packs so much. It’s always a challenge to beat the heat here in Texas, and now we are well-equipped for shopping, vacationing and keeping cooling pads and water well-chilled for our dog on our daily runs. We especially like the sensible, recyclable materials you’ve used, unlike the tons of plastic used by one of your competitors here in Austin. The Oyster is colder, leaner, lighter and sustainably constructed. Thanks for a great product!

Very appropriate name. These guys work in the 100 degree Oklahoma weather.
