The women's Brooks Shield Puffer Jacket is a performance jacket for cold-weather warmups and outdoor training. 300gsm THERMOLITE synthetic insulation adds warmth without bulk, while a DWR-treated shell helps shed light rain and snow. Cinchable hood and hem, plus elastic cuffs, help keep wind out and warmth in. Zippered hand pockets and an internal zippered pocket secure essentials, and the relaxed fit leaves room to move without feeling baggy.
