{"product_id":"aeroforce-x-ii-aero-calf-sleeves","title":"Aeroforce-X II Calf Sleeves","description":"\u003cp\u003eDeveloped in collaboration with NOPINZ, leaders in aerodynamic garment engineering, the Aeroforce-X II Aero Calf Sleeves are designed to optimise airflow around the calf during high-speed riding. The lower leg contributes significantly to aerodynamic drag, and refining airflow in this area can improve overall riding efficiency over race distance.\u003c\/p\u003e\u003cp\u003eThe sleeves use a lightweight, quick-drying technical fabric engineered to support controlled airflow while remaining breathable at race intensity. Integrated mesh zones promote ventilation and temperature regulation without compromising the aerodynamic profile. A close, contoured fit creates a smooth interface with the leg, helping reduce turbulence without restricting movement.\u003c\/p\u003e\u003cp\u003eA silicone gripper at the upper cuff ensures the sleeves remain securely in place throughout the bike leg, maintaining consistent positioning from transition to dismount. Designed exclusively for competition, the Aeroforce-X II Aero Calf Sleeves reflect NOPINZ’s race-proven approach to aerodynamic performance.\u003c\/p\u003e","brand":"ZONE3","offers":[{"title":"S","offer_id":57728025297277,"sku":"TW26UAFCS101\/S","price":79.0,"currency_code":"USD","in_stock":false},{"title":"M","offer_id":57728025330045,"sku":"TW26UAFCS101\/M","price":79.0,"currency_code":"USD","in_stock":false},{"title":"L","offer_id":57728025362813,"sku":"TW26UAFCS101\/L","price":79.0,"currency_code":"USD","in_stock":false},{"title":"XL","offer_id":57728025395581,"sku":"TW26UAFCS101\/XL","price":79.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0039\/0434\/0032\/files\/aeroforce-x-ii-calf-sleeves-high-speed-riding-aerodynamic-garment-engineering-performance.png?v=1781123363","url":"https:\/\/zone3.com\/en-us\/products\/aeroforce-x-ii-aero-calf-sleeves","provider":"ZONE3","version":"1.0","type":"link"}
