The only visible ventilation comes from these two exhaust ports on the back, but surprisingly, this is actually the most comfortable aero helmet I've used, and doesn't give me any heat problems at all.
The introduction of the Giro Selector marks the first time an aero lid was really so hotly as anticipated as some of the bigger-ticket triathlon purchases. The new lid provides cutting-edge aerodynamics along with a novel fit adjustment via two swappable tail fairings, a detachable visor, and a leaf-spring retention system that's as comfortable as it is simple. The helmet is a little tricky to adjust, but once it's on, it's the best lid I've ever used. Watch the video review for more.
In our final segment of this year's Ironman World Championships, we're going to take a closer look at the wide array of custom helmets made just for the pros.
