Description
These all-season insulated pants combine functionality and sustainability.
They are made with an innovative fabric construction to prevent marine pollution caused by microfiber shedding.
The Mono Air Pants were developed as a new generation of technical clothing alternative to fleece and are designed around the same concept as the award-winning Mono Air series. It uses Polartec® Power Air Light, specially designed by Polartec, Inc. of the U.S. to combat the problem of marine plastics, which reduces microfiber shedding by up to 80% compared to conventional fleece products. In addition, the lightweight, warm and durable fabric is made from recycled and recyclable materials, making it both functional and sustainable.
Whereas traditional fleece has exposed raised fibers that can fall out of garments during washing and use, the Mono Air Series fabrics were designed with a myriad of small pockets arranged between the outer and inner fabrics, into which bulky fibers are woven like a padding. The special capsule structure created in this way traps warm air from the body and creates insulation, while at the same time preventing the fibers from falling out. The fabric surface is also reinforced with Hardface® treatment to prevent pilling and snagging and to increase durability and water repellency, ensuring years of long wear in hard outdoor activities.
The Mono Air Pants are designed primarily as an outer layer, but can also function as a thermal layer under shell pants. The lightweight, durable, stretchy and breathable fabric makes them year-round, versatile and versatile. Designed to provide comfort for everything from extreme adventures to weekend activities and everyday lifestyle.
