What separates a good cover from a bad one is quite thin, but it makes a huge difference.

The key to Cocoon’s breakthrough in protective cover technology is a membrane that’s around 70 microns thick (about the same thickness as a piece of paper) and consists of more than a billion pores per-square-inch. It’s a very thin layer, but also a very big deal because it means Cocoon covers are air-permeable, not just breathable.

While breathability and air-permeability may sound the same, they are actually quite different. Air-permeability is what allows our covers to more quickly release heat and moisture from under a cover. A cover that’s merely breathable traps heat and moisture, creating the very conditions the cover is meant to prevent. That’s why covers that aren’t air-permeable can actually cause and/or accelerate corrosion.

It's hard to overstate the importance of that 70-micron layer in the performance of a protective cover. For decades covers have been waterproof but haven’t been able to release the inevitable heat and moisture that gets trapped underneath. Now, thanks to technical textiles and years of R&D, there’s a cover that can do both.
