Guess how many pores it takes to make our covers so air-permeable.

Air permeability is crucial in an effective cover because it prevents moisture from building up under the cover. In order to make our covers highly air-permeable, we use a patented textile that includes a remarkable membrane. 

The membrane is full of pores small enough to be fully waterproof and repel liquids, but big enough to allow vapor out. Just how small are we talking? There are over 1 billion pores per square inch in the membrane! That’s not just a surprising number of pores, it’s an amazing number of pores - an almost incomprehensible number of pores.

The people at Cocoon who work with our textiles every day are somewhat matter of fact about all this, but it remains incredible to the rest of us. Maybe that’s because we weren’t the ones who had to figure out how to laminate it with the right facing fabric and backing fabric. It turns out that the membrane is a bit of a diva.

Laminating is tricky under normal circumstances, but it’s particularly thorny when there’s a membrane involved. The membrane had to play nicely with the facing and backing fabrics, and it had to maintain its high performance post-lamination. Too little adhesive and the fabrics wrinkle or adhere unevenly when laminated. Too much glue and the membrane doesn’t perform as well.

It took a couple of years to get it right, but once we did, the membrane and its supporting cast of textiles are performing at a level unprecedented in protective covers - and those billions of pores are protecting critical assets all over the world.
