The Science of SealSkinz
Every single SealSkinz product is tested before it leaves the factory, mounted onto a machine and subjected to high water pressure.
If any product leaks, the item is rejected, meaning that every single SealSkinz product is guaranteed to be 100% waterproof. The waterproof film can withstand 10psi of hydrostatic head pressure, the equivalent of a column of water 700cm high standing on the fabric surface. This is seven times the level required to meet European Standards for waterproof clothing.
SealSkinz socks and gloves use a type of membrane called hydrophilic - water loving - which is totally solid and without pores, making it physically impossible for droplets of liquid water to pass through. It is still, however, totally breathable because water vapour molecules are transmitted from molecule to molecule through the membrane on the polymer chain, then expelled on the other side.
The driving force is the difference in humidity and temperature between the atmospheres on each side of the film. The internal climate, next to the skin, is hot and humid because the body is generating heat and moisture as it exercises, while the external climate is much drier and cooler.
This means water vapour is driven from the inside of the garment to the outside - as the foot gets hotter during an activity, so the film becomes more efficient at expelling moisture.
