The Carros de Foc loop in the Spanish Pyrenees takes you through an unforgettable 37 miles of forests, mountain passes and vistas. Fall is the time to go, and for highly aerobic activities in cool-to-cold conditions, the Wind Shield Jacket wicks, breathes and blocks wind. Its updated fabric is now warmer throughout, with the front and tops of arms relying on 100% polyester (now recycled) that’s laminated to a stretchy and breathable windproof film. The sides, back and undersides of the arms are un-laminated, using a stretchy, wicking 85% polyester/15% spandex jersey fabric. Details include a zippered media pocket (with stretchy interior phone sleeve) on the chest, reflective elements on the chest and center back, and an elastic drawcord hem. Polygiene® permanent odor control and a DWR (durable water repellent) finish.
