Ability of a fabric to let water vapor pass through. The unit of measurement of breathability is gr/sqm/24H. Procedure whereby a specific substance is deposited in the inside of the fabric in order to confer specific characteristics (waterproofness, breathability...) Synthetic film laminated to the inside face of the fabric to increase performance. Size of micropores that let the moisture exit and prevent moisture (rain, snow) from going through As body temperature rises, the membrane's molecules move more actively, expanding the inter-molecular gaps to accelerate the fabric's moisture permeability. Property of a fabric to resist water penetration.
Lightweight fiber to stuff a garment and which provides heat and moisture transfers. Waterproof tape is sealed at high temperature on seams to guarantee waterproofness. The seams are either partially (hood, shoulders…) or fully linked together. Outside fabric combined with a membrane to provide the product with optimal waterproofness and breathability. These jackets have an independent liner to protect the membrane..
These jackets are easily identifiable with an outside fabric combined with a membrane which is printed on its inner side. This “print” protects the membrane against abrasion or possible damage. This combination makes the jacket lighter and compactable. These jackets are usually worn on bare skin. A membrane is incorporated and pasted between an outside fabric and a mesh. In this case, the three layers work together making the jacket sturdy, waterproof and breathable. Ability of a fabric to prevent moisture from going through it. The unit of measurement of waterproofness is the Schmerber, expressed in mm. Ability of a garment to prevent wind from going through and 2-layer jacket. Outside fabric combined with a membrane to provide the product with optimal waterproofness and breathability. These jackets have an independent lining to protect the membrane.
