The Vanguard helmet sets a new standard for full-face mountain bike helmets. In addition to high safety and good ergonomics, which all these helmets must meet, they also offer two other things that are merely dreamlike in many models. It is an extremely low weight (725g in size M) and highly efficient ventilation that you are accustomed to from road bike helmets. No more taking off the helmet to relieve yourself from heat and heavy weight! If you expect any compromise or limit of use, you are mistaken. Vanguard is fully certified for even the most demanding use thanks to numerous tests. So, it's Downhill ready, and that means something.
