It’s extremely difficult for me to put on a helmet in the summer. My head begins to sweat, and I soon find myself wiping the moisture from my eyes. This is where the ABUS Yadd-I comes in. While it may not appear to be sufficiently ventilated, the location and design of vents generates a “forced air” effect that has shown to be rather effective. My head still gets hot, but I’m not drenched in perspiration when wearing it. The cushioning may be removed and washed to get rid of any scents that may develop over time.
