Fahrenheit Primaloft Gelanots Urban Plus Winter Jacket | Grey

The new Fahrenheit Gelanots Urban Plus warm jacket for cold temperatures. Outer fabric: the Gelanots Lamination membrane from Japan's Tomen (Toyota Corporation). This clever, non-porous membrane adjusts its vapor permeability depending on activity - the temperature under the garment. Provides protection from wind, water and high breathability.
The Gelanots® fabric is developed by Tomen (Toyota Corporation) of Japan and is the world leader in breathable fabrics. Gelanots® is a durable, high-elastic, non-porous membrane.
PrimaLoft is a synthetic material with high thermal insulation properties. When creating it, Albany Interional studied very meticulously the structure of goose down and put it into the basis of PrimaLoft material. The fibers of this insulation are very thin and resemble goose down more than any other synthetic material. It is this similarity that gives it the thermal properties of down. The coefficient of thermal resistance for goose down is 2.18, while for PrimaLoft it is 2.15. This is a very high figure, because other synthetic fibers do not even approach this value.
The PrimaLoft fill has a long-fibre structure that enables it to recover its volume better and faster than similar materials. Even after a great number of washings and dryings, the material does not deform. The fibers are endowed with water-repellent properties, which help any liquid to run off or evaporate. It provides constant dryness of PrimaLoft insulation products.
Vapor permeability
The secret of the Gelanots® membrane lies in the highly permeable molecular structure of the special polyurethane (PUR) from which it is made. The hydrophilic PUR molecules are spaced far enough apart, and the mutual attraction with water molecules creates optimal conditions for high vapor permeability.
During increased physical activity, large amounts of sweat, vapor and condensation accumulate under clothing. Vapor molecules are attracted to the Gelanots® membrane, pass between the PUR molecules and temporarily become part of the membrane (hydrophilicity). Subsequently, the force created by the difference in partial pressure between the outside and inside of the garment and the elevated temperature on the inside of the membrane pushes the sweat molecules outward.
Gelanots® are called the "smart membrane". When actively engaged in sports, a person not only sweats a lot, but also generates a lot of heat, and under the influence of high temperature PUR molecules move faster, the distance between them becomes larger and, as a consequence, vapor permeability increases.
As physical activity increases, the temperature inside increases, the temperature gradient increases, sweat begins to evaporate more intensively, condensation accumulates on the inner surface of the membrane, and humidity increases. With Gelanots®, hydrophilic molecules continue to attract, promote and push condensation outward, unlike classic pore membranes where condensation can create a coherent layer, causing the pore membrane to stop breathing.
Sometimes, especially during rain, there is no gradient in the partial pressure of water vapor. Under such conditions, the Gelanots® membrane continues to operate due to temperature differences.
