Short boxy padded jacket with FELLEX® AEROGEL filling. FELLEX® AEROGEL technology is made from 95% polyester and contains an AEROGEL component that increases thermal insulation without adding extra weight to the garment. This material is used in astronauts’ suits because of its lightness and warming capacity. Breathable, water-repellent and wind-resistant fabric. High neck and front button fastening. Buttoned side pockets. Cuffed sleeves. This jacket has been tested to withstand temperatures from +11ºC (low activity) to -13ºC (moderate activity) during a standardised test with simulated wind of 0.4m/s wearing a long-sleeved high-neck T-shirt, trousers, underwear, socks, shoes, gloves and a knit hat.
