A long-sleeved bike shirt designed for the most demanding. 4.0 Ultraweld is the technical cycling jersey made of ultra-light elastic knit fabric, with moisture-resistant MoistureCool material and ventilation channels. The tight race fit makes it usable with or without protective clothing, and, like few bike jerseys on the market, it is compatible with neck braces. The elbows are reinforced with Brush Guard and an ultra-flexible, lightweight film increases resistance to scratches and abrasions. Furthermore, the 4.0 Ultraweld bike jersey offers heat-sealed seams on the cuffs and hems to ensure maximum comfort and non-slip silicone parts that allow it to always stay in place.
