Sweatpants with Elastic Hem Made From Cotton Jersey with Color Blocked 'Rain System" Fabric from Loro Piana. The delicate combination of color nuances between Loro Piana nylon and Giza cotton sweatshirt gives the garment refinement, ideal for leisure. The exclusive rain system treatment owned by Loro Piana forms an invisible barrier around each fiber, protecting it from dust, dirt and water-based stains. To increase its effectiveness, rain system pfc is used in combination with hydrophilic membranes. The hydrophilic Loro Piana membranes applied on the reverse side of the fabric are resistant to water and wind and maintain the body microclimate in ideal conditions. Giza cotton, also known as the queen of Egyptian cottons, grown in very restricted areas in the Nile delta, is the finest micron-aire fiber in the world (2.8) resistance, extraordinary brilliance and softness. A limited quantity of fiber and a high cost of sowing and cultivation preserve the quality of an exclusive product.
