What Our Gearhead(R) Experts Are Saying:"I throw on the Classic Retro-X Vest for everything from shoulder-season hikes to everyday errands. The fleece is incredibly cozy, and the windproof lining keeps cold gusts out without overheating. It's the layer I never leave behind when temps start to dip."We reach for the Classic Retro-X Vest when we need core warmth, timeless style, and a touch of mountain heritage. Patagonia's signature half-inch pile fleece feels soft against the skin and is made with 100% Repreve(R) recycled polyester, offering cozy insulation that honors the places we love to explore. A windproof barrier and moisture-resistant taffeta lining work together to shield us from chilly breezes and light flurries, while the relaxed fit layers comfortably over flannels or hoodies. Trim and lining are bluesign(R) approved and made with NetPlus(R) nylon from recycled fishing nets, making this vest as planet-friendly as it is versatile.
