Like almost all Helly Hansen products, the Sirdal Hooded Insulator Jacket is made from high-performance, eco-friendly materials that let us enjoy nature without trashing it. The ECOLoft Air SR Insulation provides excellent warmth for the weight, insulates when wet, and includes recycled materials that reduce waste, consumption, and emissions. The jacket also features a PFC-free durable water repellent to shed light rain and snow, so we can stay drier and warmer as we enjoy hiking, camping, mountaineering, and everyday living in our puffy jacket.
