What Our Gearhead® Experts Are Saying: “These are the pants I reach for when it’s storming but I still want to move freely. The Blackside Pant’s 4-way stretch keeps me comfortable on long runs, and the PrimaLoft® insulation adds just enough warmth for cold lift rides. The fully taped seams and waterproof zippers mean I never worry about wet chairlifts or deep snow.” We count on the Rossignol Blackside Pant for performance and protection when the snow is flying and the mountain calls. Built from recycled 4-way stretch twill with a 20K/20K waterproof breathable laminate, these pants move naturally while sealing out the elements. The classic fit provides enough room for layering without bulk, keeping our stride smooth from bootpack to après. Inside, lightweight PrimaLoft® Black insulation delivers just the right amount of warmth for frigid mornings while staying breathable when the pace picks up. Fully taped seams, waterproof zippers, and a PFC-free DWR finish ensure total weather defense through storms and powder days alike. Details like removable suspenders, adjustable waist tabs, and pre-shaped knees let us dial in the perfect fit, while integrated boot gaiters keep the snow where it belongs—outside our boots.
