What is WP?
Pages that contain Softshell Jackets have also information like WP 1000, WP 3000 or WP 5000.
WP symbols are indicating how waterproof jacket is (WP is abbreviation for Waterproof). In other words, it means how much water pressured against the cloth will not penetrate the jacket in 24 hours time.
Amount of water is measured in milimetres, [mm]. Hence, WP 1000 means that softshell is able to prevail 24-hours of 1000mm water pressure and it will not soak.
Higher the number, the better, albeit it is worth noticing whether jacket has taped seam or not. Lack of it make jacket soak despite of high WP.
What is MVP?
MVP is abbrevation for Moisture Vapour Permeability. It indicates that breathable membrane measured in grams [g], is included in jacket and it transfer water gathered inside to the outside.
MVP 1000 means that about 1000 g will vapour out on 1 metre square of material. Factor is crucial because it prevents that sweat will adhere to the body and endanger person who wears it for getting cold.
Hight WP is useful in case if you are planning wearing softshell during sport activities.
