Under Armour Men's Threadborne Siro ¼ Zip

• Threadborne Siro fabric gives greater stretch & recovery, ultra-soft feel & more breathable performance
• Material wicks sweat & dries really fast
• Under Armour’s mission is to make all athletes better through passion, design and the relentless pursuit of innovation
• Where we started? It all started with an idea to build a superior T-shirt
• The technology behind Under Armour's diverse product assortment for men, women and youth is complex, but the program for reaping the benefits is simple: wear HeatGear when it's hot, ColdGear when it's cold, and AllSeasonGear between the extremes.

Using new manufacturing techniques, Threadborne Siro fabric is built to eliminate distraction. We‘ve engineered it to keep the ideal distance between fabric and athlete, so it won't cling when wet and dries incredibly fast.
