Like no other sports glasses, the SIOLS-Indoor is optimized for indoor sports: The frame of the glasses is absolutely splinter-free, without metal parts and sharp edges. It sits firmly on the head thanks to a length-adjustable headband. The 3-point nose and side impact protection deflects the effects of an impact with the help of Empilon cushions. The SIOLS.Indoor sports glasses are open at the top and at the sides. Congested heat can escape and the sports glasses do not fog up. If desired, the optician can install additional ventilation channels. The SIOLS.Indoor is a Category 2 individual protection product in accordance with Regulation (EU) 2016/425 and the EN 166:2001 standard.
