In comparison to my last two helmets, one of which was a Louis Garneau Carbon Titan and the other a Bell Alchera, this helmet is the king of helmets. Incredibly light. I forget it's there sometimes. It has a very low profile, which bothered me about my LG. It looked bulbous. This is is tiny.
I always found myself having to adjust my click-lock tightener throughout a single ride, and definitely if I chose to ride with a cycling cap or sweatband on, but the elastic stretch that they integrated got rid of all of that trouble. I haven't had to adjust it since the first ride. It's also very, very comfortable. It feels very secure.
X-Static pads are holding true to their word. Helmet smells great after approximately 800 miles put in on it in the Texas heat.
Don't have any trouble with ventilation. I feel like it has an adequate amount of vents.
I have a 53cm head, and the small fit like a dream.
Definitely plan to buy another if I crash this one.
