IN WATERPROOF APPAREL AND EQUIPMENT.

Key features

The Shield Air membrane is a precisely engineered, electrospun nanofibre web, with an open network of interconnected pores. These small and consistently sized pores present little resistance to moisture vapour, whilst providing an effective barrier to liquid water. Crucially, whereas many other waterproof breathable membranes have zero (or close to zero) air permeability, the open structure of the Shield Air membrane allows air to pass through, whilst still offering effective wind resistance.

Characteristics / Benefits

High level of airflow facilitates significant rates of water vapour permeability
Warm, moist air is driven through the fabric by convection, before it can accumulate inside the garment – significantly raising user comfort
Standard vapour rate (MVTR) tests do not capture Pertex Shield Air's full in-use comfort benefit

Nanofibre membranes typically suffer rapid decline over successive washes
Advanced lamination techniques, and precise control of membrane density and structure provides durable waterproof protection, even after many wear and wash cycles

Options and variations

Developed over decades, our expertise in lightweight woven fabrics provides for multitude of Shield Air construction options, allowing deep product differentiation.

Solution-dyed yarn

Other yarn

Solution-dyed fabric is dyed through the entire filament, completely integrated with the material
Colours are more vibrant and long-lasting, fade and stain-resistant with enhanced durability
No water is used in the solution-dyeing process, and significantly less energy is used

Section view of diamond fuse filament

Pertex Diamond Fuse filaments have a uniquely engineered rhomboid form, interlocking to create highly stable and durable yarn structures
Fabrics created using Diamond Fuse yarns have enhanced snag and abrasion resistance, remaining stable over extended wash and wear cycles

Responsible material options

Our partner Bureo works directly with fishing communities to collect their discarded fishing net waste and bring positive, end-of-use solutions to the most harmful form of ocean pollution.

These nets are recycled into nylon pellets, spun into yarn and woven to create Pertex fabrics.

Netplus post-consumer recycled nylon

We recover waste material from the production process, to be recycled into nylon pellets, thereby reducing use of virgin fossil fuel derived inputs.

pre-consumer recycled nylon

We recover waste material from the production process, to be recycled into nylon pellets, thereby reducing use of virgin fossil fuel derived inputs.

Post-consumer PET waste is mechanically recycled back into polyester pellets.
