For an added touch of warmth, slip on the Helly Hansen Men's Lifa Pants before you head out for a day of shredding, snowshoeing, snowmobiling, or your winter adrenaline rush of choice. Helly Hansen's lightweight Lifa fabric is designed to release excess body heat and quickly dry built up sweat while still providing durable insulation. Flatlock seams, the elastic waistband, and form-fitting design all offer the most comfortable fit possible while you're getting after it outside.
