With PEARL iZUMi's Expedition Pro Alpha Jacket zipped up on our body, we won't have to question riding outside on a cold day again, knowing how warm and comfortable it keeps us. The Toray ultra-light woven fabric offers protection against the wind and optimal breathability. Meanwhile, 60g of Polartec Alpha Direct active insulation throughout the arms and body ensures we stay at the perfect temperature, but the underarms and waist feature a lightweight stretch woven fabric to allow heat to escape if necessary.
