The exterior and lining of the jacket are made of 100% recycled polyester. Lightweight Polartec Alpha active insulation provides core warmth while still being surprisingly breathable. Four-way stretch fleece on the sleeves and side panels promotes mobility, enhances breathability, and helps to wick moisture to keep you dry and comfortable during aerobic activities.
