"What Our Gearhead® 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® 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® approved and made with NetPlus® nylon from recycled fishing nets, making this vest as planet-friendly as it is versatile."
