Born cold for the street and summit. The new Sierra Jacket features Gilltek technology, 750 fill power duck down insulation and taffeta fabric giving it a sleek, classic look, while also offering superior warmth. The fabric is finished with our Eco-C0 DWR treatment, giving it added water resistance to preserve loft even in wet or snowy conditions. The comfort and versatility of this one-of-a-kind insulator has made the Sierra Jacket a favorite amongst ski towns on local streets and global slopes. Team it up with our Snow Drop Pant and let everyone know the style you were born with.
