The high breathability fabric inserts on main perspiration areas ensures the best comfort and a perfect fitting. The super-light OMP Tecnica long sleeve top is made of a very smooth soft knit blend of flame-retardant aramid fibers. You really don't need to wear an undershirt under this top! Special extra-breathable fabric are strategically placed to allow perspiration to evaporate without sacrificing protection. External flat seams add to comfort. OMP Tecnica Top features long sleeves and a mock turtleneck. FIA 8856-2000 homologated.
