The Alpha Trail jacket from Santini is a revolutionary product. The outer layer of lightweight windproof woven fabric is enriched inside with a Merino wool-based Polartec® Alpha® fabric that adds warmth without adding weight to the jacket. Polartec® Alpha® can regulate your body temperature and provide excellent breathability in changing conditions, while wicking moisture away quickly. A small zipped chest pocket allows you to store personal items, while mesh back pockets, reflective detailing and an ergonomic fit add to the garment's practicality and ensure exceptional comfort. - Recommended temperatures from 0°C to +10°C - Outer lightweight windproof woven layer - Merino wool-based Polartec® Alpha® - Zipped chest pocket - Double front zip - Triple mesh back pockets - Reflective detailing on back for high visibility
