GlossGORE-TEX® ProProvides the highest level of durable waterproof/breathable performance available. GORE® Micro Grid Woven Backer delivers garments that are consistently the lightest and most compact in the industry. GORE-TEX® Pro has a sparsely woven nylon backer that is twice as durable as traditional tricot liners and allows moisture vapour to pass quickly through to the GORE-TEX® membrane.
N40r GORE-TEX® Pro 3LA high tenacity nylon face fabric with a flat filament warp and false twist fill textured yarns. This lightweight ripstop fabric has a micro-grid woven backer and DWR finish
N70p GORE-TEX® Pro 3LA lightweight, soft feeling textile. The tightly woven construction features a plain weave with textured false twist fill yarns. Highly abrasion resistant for its weight and soft hand. Durable Micro Grid woven backer and DWR finish.
DWRA finish applied to a fabric that will bead-up water on its surface to stop it soaking into the fibres. This maintains breathability and shortens drying times
Keprotec™ Made with reinforced Kevlar fibres, it is extremely resistant to cuts and abrasions, as well as oil, water and general dirt.
E3D patterningErgonomical 3-Dimensional patterning brings an additional level of articulation to provide enhanced mobility. E3D refers to an allowance in the garment patterning to provide extra gusseting and/or articulation in key joint areas to allow for maximum movement.
WaterTight™The world’s first WaterTight™ zippers to pass the W.L. GORE® extreme wet weather test.
