The Limar UltraLight Road Bike Helmet provides all the protection you'd expect from a high end road helmet in a super lightweight package. At a claimed featherweight of 175g for a size medium, you'll barely notice the Ultralight once you clip in. Limar uses double shell in mold construction to provide impact protection and 22 air vents to move cooling breezes across your dome. This helmet also features a bug net across the inside of the front vents, which is something you don't see often in cycling helmets but we think is a fantastic idea for keeping pesky creatures out of your hair. The Ultralight Road Bike Helmet comes complete with Limar's Ultrafit adjustment system with height adjustment for a quick, customized fit every time you ride. Antibacterial padding on the inside of the helmet provides soft cushion and fends off those funk producing single cell organisms.
