Wear a Terra Peak jacket to protect you from the cold while hiking, thanks to Thermoball? insulation and windproof WindWall? fabric that keep you warm even when wet. Durable recycled tear-resistant fabric makes this jacket a durable option, while the bezel design (with zippered pockets and brushed knit lining on top of the windshield) brings some street style to the mountains. There are also breathable wool panels under your arms that control airflow to help you maintain a uniform temperature. When the sun comes out, the entire jacket can be tucked neatly into your hand pocket, taking up less space as you move around.
