The Smart-Therm gilet acts as an essential outer or mid-layer when worn under a shell jacket. By targeting areas most affected by colder conditions using insulated panels, this jacket produces and retains body heat to keep you protected from the elements. The game-changing Y-shape back and side panels are highly breathable and fleece-lined with multiple ventilation grades to ensure maximum airflow in areas that require less heat production and more breathability. * Super lightweight and great for packing down when on the go * PFC-free DWR treated shell fabric that is wind-resistant water resistant and breathable * Reflective strip prints at centre back for increased visibility * Zip side pockets to keep possessions safe and secure * HL branded stretch binding at hems * Recycled and slimline faux down wadding to increase thermal insulation in areas most affected by the cold without the bulk. 150gsm (Body) * Triangular HL zip pullers * Inner storm flap to prevent wind penetration through zip teeth
