The Zip is covered by two wind and storm baffles which Velcro over each other, the bottom of skirt has elasticated shock cord and toggle adjustment to bring this area close to the body and prevent wind from driving up from below.
These products are breathable/permeable...
British Army issued kit made of the original “Goretex” or “MVP” aka Moisture Vapour Permeable material are “breathable” products, ok, that sounds good, but what exactly does it mean, let’s make it simply for you, the customer to understand:
When it comes to outdoor wear, from trousers to jackets or mid layers, the best and most useable fabrics are “breathable”, arguably more important than being windproof or waterproof, breathable capabilities in a garment mean it allows body moisture and vapours to be released, so you can use it for active wear without overheating or feeling discomfort.
Breathable garments do not ‘stop’ you sweating or producing moisture, which is a natural response, but allow drying to happen quickly.
Breathability is particularly important in active wear. The more of your own body heat you will be using and producing, for example on an uphill trek, the more breathability you will need.
The balance with breathability is between letting enough moisture escape, whilst keeping moisture out, whilst at the same time preventing condensation.
