The Strato is an extremely affordable bike helmet for athletic men and women who can appreciate a bit of spice in the styling. The helmet has in-mould construction with 20 ventilation openings, so cooling is no problem. Just as all of the other AGU helmets, the Strato complies with the legally mandated safety requirements such as EN1078. With its extremely low weight of 240 g and camlock closures, you'll barely notice the comfortable Strato on your head. And this helmet also has the practical Direct-Dial adjustment system, of course, that you can adjust with one hand.
