The Fundango Sierra Heather Pants men's ski pants let you enjoy the snowy slopes with abandon! The premium synthetic filling of these ski pants keeps you warm in cold winter weather without sacrificing ventilation. The snow guard prevents snow from getting under your clothing even on the biggest drops, and the reinforced ankle protects your feet from ski injuries. Zippered side pockets and back pockets keep your valuables comfortably stowed. Zippered vents let you easily regulate heat dissipation. DWR water-repellent treatment prevents water droplets from sitting on the fabric, collecting as tiny beads and then rolling off the pants. The development of the high quality Dripex membrane used for the track pants was inspired and helped by athletes training in extreme weather conditions. To meet their demands, the Dripex lubrication or lamination, which protects and reinforces the fabric from the inside out over its entire width, does not let in cold wind or unwanted moisture under any circumstances, while leaving the outside free to sweat from active movement. The value of 10 000 mm means that every square centimetre of the trousers must be able to withstand the pressure of a column of water at least 10 000 mm high without letting moisture through. This value is a sign of premium class clothing: even in torrential rain, the pants remain impervious to water. Made with a detachable and adjustable bridle, these customisable track pants have a breathability of 8000 g/m2/h.
