Whether you're planning a winter summit hike or a backcountry ski trip, you'll love the flexibility and warmth of The North Face Catalyst Jacket. Part of the Summit Series, this luxurious and lightweight jacket packs it in with 800-fill goose down fill and special Pertex Quantum fabric on the exterior that's designed for resistance to wet and snowy weather. The North Face Catalyst also has an alpine fit for good coverage right past the hips, plus elastic cuffs and a cinch-cord waist for chasing the chill at your vulnerable spots. Outdoors women really love this jacket because it crushes down easily, using a special bag built right into the front pocket, and it layers easily under a shell or can be worn separately on warmer days or on short day trips. With its warmth, usability and weather repellent fabric, the Catalyst Jacket definitely gets one big thumbs up.
