If you are looking for a lightweight hooded insulation layer and would prefer a synthetic alternative to down then the Ascent S-Thermic Hooded jacket could be just what you need. The insulation is a unique combination of 60g G-Loft Eco which is used in the lower front body, the back, sides, arms and hood. Insulation in the front upper chest is crafted from Primaloft Thermoplume which is a synthetic alternative to down made from 100% PCR plastics. A super-soft and stretchy outer fabric allows for great air permeability in order to prevent overheating during activities. For added heat regulation an additional stretch knit fabric is placed under the arms to allow warm air to escape. The hand pockets and inner chest pocket have brushed comfort linings to keep your hands cosy as well as protecting your smartphone's battery. An adjustable hood and lower hem allows you to fine-tune the fit for optimum comfort and to keep out cold blasts of air.
