Lazer's Z1 FAST helmet features an integrated, non-removable cover attached to the EPS liner to create an unbeatable advantage. Because of the one piece shell, it cuts through the wind like no other road helmet. The shell closes of most ventilation holes to create a super-slick surface that glides through the air with significantly less resistance. Tests have proven that the Z1 FAST helmet can provide gains between 4 to 10 watts when cycling at 45 kph, or a difference between 12 to 30 second over 40 kilometers. That could be the difference between standing around watching the podium ceremony versus being on the top step!
