High performance long john, 3-layers, 4-way stretch fabric (including the membrane, which makes the fabric 100% elasticated). Very light and very strong. 100% waterproof with thermo-taped seams and extremely breathable.
3-layer processing consists of a tri-laminated structure formed by 3 superimposed layers of fabric." To make a laminate, a breathable and waterproof membrane is joined to a high-performance technical fabric. With a 3-layer fabric an additional lining is not required, which ensures that the garment is lighter, more breathable and comfortable, with faster drying.
A breathable fabric allows the perspiration produced by physical activity to pass through it. The breathable nature of the fabric promotes biological breathability which allows body moisture to be expelled easily, thereby decreasing condensation from perspiration, increasing comfort. A breathable fabric measures the water vapor, expressed in grams, that crosses an area of 1 square meter in 24 hours (g/m2-day).
Extremely lightweight fabric that enables maximum body breathability.
Thermo-taping involves the hot application of a seam tape on the back of the fabric to prevent water from entering through the micro-holes in the seams. The total waterproofing of a garment is guaranteed by using waterproof fabric and thermo-taping the seams.
Waterproofing is the technique that makes a fabric water and wind resistant. These properties can be achieved by treating with water-repelling substances or through the use of a mechanically-activated hydrophic/microporous membrane. Waterproofing is expressed in millimeters, which represent the water column height the fabric can withstand before liquid penetrates.
