Burton L43205 Womens Forest Night Arliss Insulator Jacket Size S 

A good-looking tech jacket made from bluesign-approved textiles features Burton’s Living Lining that offers automatic temperature control—when you heat up, breathable micro-openings in the Living Lining expand to release excess warmth and prevent overheating, and when you’re cold, the same micro-openings contract to preserve your body heat, helping you stay warmer.
