Sportful expertly crafts the Fiandre Strato Wind Jacket to have the wind blocking of a vest with the comfort of our favorite long sleeve jersey. Using Gore-Tex Infinium, the front panel offers a double layer for warmth and windproofing, while two hidden zippers allow for greater ventilation when needed. The stretchier and more breathable sleeves and back panel help us stay cool and dry as we train through the shoulder season.
