Simple. Analog. Reliable — by design.
It just fishes great.
a Standard Cover you can stand on?
Yep.
In all our testing of the Hot Flex 2, we observed several shortcomings with foam covers. They tend to become brittle in colder temperatures, easily blow away in the wind, and often shed particles into the ice. This led us to design the Cold Flex 12.
Through rigorous testing, we found that the Cold Flex 12 matches or surpasses the temperature performance of standard covers, which typically function well above 15°F.
Additionally, it's stiff enough to stand on, making it an excellent option for both portable setups and fish houses—keeping your gear out of the drink!

Cold Flex Cover
MADE IN MINNESOTA!
In the land of 10000 lakes there is no shortage of Ice in winter. Giving us plenty of chances to learn how to deal with it!
How the Idea came to be could not be more funny, or Minnesotan. After attending the coldest outdoor NHL game ever, I had a bunch of hand warmers left over and just laying around. At the time I was also dealing with freezing problems at our cabin and dealing with them. Really the aha moment was that at 33 degrees the pipes don’t freeze. Then one day staring out at the lake at -15 it came time for a fishing trip and after fixing the frozen pipe problem, I figured I could I fix the frozen Ice hole problem and Voila! The Ice Hole Heater was born!
I have been inventing and making things professionally since 2016. Your satisfaction is 100 percent guarenteed. These really do work just that good! You can check out all my other work at www.cabincustoms.com
