Mountain Biking Showerproof Jacket 900

Waterproof and resistant to wear; for MTB.---specs--- Waterproofness Waterproofness is a fabric's ability to prevent rain water from passing through. A fabric's waterproofing is de termined by measuring its resistance to the pressure exerted by a water column, measured in mm (test based on ISO 811 standard). The higher the pressure, the more waterproof the fabric. Material with a waterproof rating of 2000 mm resists the pressure exerted by 2000 mm of water (which roughly corresponds to a 2-hour rain shower). Breathability To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapor produced by the body escape, and therefore the more breathable it is. For example: RET Show more
