The Oakley FGL Fuel LS Shirts 5.0 is based on a fabric with excellent water repellency, moisture permeability, and elasticity, and the highly breathable high-performance material actively expels moisture from inside the garment through a special knit, keeping the wearer dry and comfortable at all times. In addition, the water-repellent technology keeps the garment protected even in bad weather. The high functionality achieved through repeated field testing maximizes its potential in a variety of environments.
