“The Sine Thesis is very well made and very comfortable. It has bold, angular styling that gives it an almost aggressive look but there is certainly no denying the quality.
“The Sine Thesis has proven to be one of the most comfortable helmets I’ve worn, easy to adjust and better to wear. Comfortable, light lid that provides plenty of protection without compromising style.” -
