Fox Bionic series synthesizes form and function through bonding technical fabrics while also keeping the performance and cutting edge Fox style. The result from these two elements has resulted in the creation of the Fox Bionic Humphrey Jacket. This jacket has micro-porous coatings that are 2000 mm waterproof with durable water repellant coating and 3000 mm breathability. These coatings are laminated to the underside of fabrics. Invisible to the naked eye, the pores are large enough to allow perspiration vapor to escape, but small enough to create a weather-proof seal against rain and snow.
