"What Our Gearhead® Experts Are Saying:""I've run in a lot of windbreakers but the GOREWEAR Concurve Windbreaker is genuinely in a different category for next-to-skin comfort thanks to the specially woven anti-wet-cling interior that keeps fabric from ever feeling damp or clingy against the skin. The kinetic design construction moves so naturally with a running stride that I completely forgot I was wearing a shell within the first mile.""Most windbreakers ask you to accept a tradeoff between protection and comfort, and the GOREWEAR Concurve Windbreaker was designed to refuse that deal entirely. Soft, supple, and highly breathable, it brings a specially woven anti-wet-cling interior to a category where next-to-skin comfort has historically been an afterthought. The interior structure reduces contact points between fabric and skin so sweat has fewer surfaces to cling to, keeping the feel dry and comfortable from the first mile through the last no matter how hard the effort climbs. At just 5 oz built from a nylon and elastane blend with recycled content throughout, it disappears on the body while blocking wind effectively enough to change the character of a cold, breezy run day. GOREWEAR's kinetic design optimizes the fit specifically around running movement so nothing pulls across the shoulders or restricts arm swing mid-stride. A lined, ergonomically shaped collar handles wind at the neck with comfort rather than bulk, and elastic cuff inserts seal things at the wrist without limiting range of motion. The full front zip hands ventilation control directly to the runner, and a drawcord hem lets you fine-tune coverage to conditions. Reflective details run across the cuffs, elbows, shoulders, waist, and center back for visibility from multiple angles in low light, and the entire jacket stows into its own pocket when the wind drops and the layer is no longer needed."
