The Helly Hansen Lifaloft Hooded Insulator Jacket works well as an outer layer during fall or spring hikes when the weather is less than ideal, and it can be worn as a midlayer when we're taking runs at the resort. It's made with a windproof shell, treated to shed light rain and snow, and filled with lightweight synthetic insulation that keeps warm even in wet conditions. Elastic at the hood and cuffs help seal out the chill, and the hem features a drawcord closure to lock in valuable body heat.
