Pertex Equilibrium
The unique structure of Pertex® Equilibrium created a comfortable microclimate by balancing weather protection and breathability. Pertex® Equilibrium uses a double weave construction in which a tightly woven outer face provides protection from the elements whilst a more openly woven inner face helps to move moisture away from your body.
Gradient structure helps to move moisture away from the user
Pertex® Shield fabrics provide lightweight waterproof protection whilst remaining highly breathable. Designed for intense mountain pursuits where weight and breathability are key, Pertex® Shield fabrics allow you to move fast and stay comfortable. The versatile 2, 2.5 and 3-layer constructions combine lightweight face fabrics with waterproof, windproof and breathable membranes. A durable water repellent (DWR) finish applied to the face fabric sheds rain and snow, which helps to maintain breathability.

Pertex® Quantum (formerly Pertex Classic, Mircolight, Quantum and Quantum GL)
Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft. Precisely constructed from incredibly fine yarns, Pertex® Quantum fabrics are designed to trap still air and improve the efficiency of insulation. A durable water repellent (DWR) finish sheds light rain and snow to provide additional weather protection.

Pertex® Quantum Pro (formerly Pertex Endurance)
Pertex® Quantum Pro uses an ultra-thin water resistant coating to provide increased weather resistance for extreme conditions. By combining a tightly woven face fabric with a microporous coating, Pertex® Quantum Pro delivers a very high level of water resistance whilst remaining lightweight, soft and breathable. The increased weather resistance and durable construction means these fabrics are ideal for use in cold or damp environments where keeping warm and dry is crucial.

Pertex® Quantum Air (formerly Pertex Mircolight)
Pertex® Quantum Air is engineered with increased air permeability to provide a balance between wind resistance and breathability. The more openly woven structure of Quantum Air fabrics allows airflow through the fabric, which helps to regulate your body heat and keep you comfortable for longer. This balance of air permeability and wind resistance means Pertex® Quantum Air fabrics are perfectly suited to intense mountain pursuits. A durable water repellent (DWR) finish sheds light rain and snow to provide additional weather protection.
