Pull on the Terra Peak Jacket and keep the cold at bay while you hike, courtesy of warming-even-when-damp ThermoBall Eco insulation and wind-blocking WindWall fabric. Hardy recycled ripstop makes this jacket a durable choice, while the baffled design - complete with zipped pockets and a brushed tricot lining at the top of the draft flap - brings some street style to the mountains. There are air-permeable fleece panels at the underarms, too, which control airflow to help you maintain an even temperature. When the sun comes out, the whole jacket packs neatly away into a hand pocket so that it takes up less room while you're on the move.
