WHY IS BREATHABILITY IMPORTANT?
The ability of a jacket to allow perspiration to escape is as important as not letting water in, especially if you will be doing anything energetic. If a waterproof jacket is not breathable, sweat will be unable to escape, making the user feel damp. It is common for people to feel as though their waterproof has ‘leaked’ when in fact it is perspiration from the inside they are feeling.
