Structured shape, "trucker" style cap constructed from British Millerain's innovative TekWax cotton. Featuring an adjustable fastening with "ThruDark" branded closure, reflective Insignia and Union flag tab. With six generations of textile innovation behind it British Millerain is not just the original, but the global leader in waxed cotton. Lancashire born, the company produced its first patented rainproof finish in 1894. After more than a century of refinement, research and redevelopment, British Millerain’s TekWax® cotton comes to ThruDark. The reason waxed cotton works so well as a water resistant barrier is that its hollow fibres are able to be filled up with, and hold onto, wax, rendering the fibres watertight. However, what sets British Millerain’s TekWax® cotton apart is its ultra-dry finish. This gives your ThruDark garment all the functional performance of a classic waxed piece without the dampened feel of traditional waxed cotton.
