Sleeveless technical gilet with body padded with FELLEX® VOLCANIC filling. FELLEX® VOLCANIC technology is a functional filling of polyester blended with nanoparticles from volcanic eruption. The volcanic minerals absorb the far infrared from the human body faster than ordinary insulation and convert it into thermal energy storage. These minerals also provide maximum odour-control technology. Front zip fastening. Zipped side pockets. Breathable, wind-resistant fabric. This jacket has been certified to withstand temperatures from +16ºC (low activity) to -4ºC (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.
