The ArcTeryx Strato Jacket is totally going to be your best friend on the slopes. This insulating fleece jacket is basically built for snowsports. Warm enough to keep you comfortable in cold conditions, but lightweight enough to keep you on your feet, the ArcTeryx Strato goes easily from the backcountry to the city streets. The Strato Jacket is made from Polartec Thermal Pro Cobble fleece, which is moisture wicking and breathable to help regulate your temperature during strenuous activity.
The Polartec Thermal Pro keeps you warm, but the ArcTeryx Strato has features galore to keep you even more comfortable. I get so comfy in mine, I just fall asleep wherever I am. No I don't, that's a joke. Anyway, check out the gusseted underarms, for example: this feature keeps the jackets from riding up, and letting the cold in. The full front zip with interior laminated windflap keeps out the cold wind. Durable Water Repellant (DWR) finish beads water on the surface of the Strato Jacket to help keep you dry in wet or snowy conditions.
Check out this insulating mid-layer fleece for everybody: there's the Men's ArcTeryx Strato Jacket, and Women's ArcTeryx Strato Jacket. If a hoodie is more your style, and you like it when your neck is really warm, check out the Men's ArcTeryx Strato Hoody or Women's ArcTeryx Strato Hoody. The Strato Hoody has all the rad features of the Strato Jacket, plus a comfy hood with laminated brim to maintain its shape and and improve visibility.
