This helmet gives less weight and less need for extra padding that would weigh down any other helmet. For awesome comfort and protection, Louis Garneau's Exo-Nerve boasts 29 vents, Garneau's Spiderlock Elite retention system and Garneau's Exo-Nerve and Titanium Ring reinforcements. This great lid also boasts moisture-evacuation channels which ensure you stay dry and comfy on every ride. This is an elite helmet offering high end performance, sleek streamline design, and full internal reinforcement.
Strengths: I got this helmet on sale for $67.00 at Performance. You cannot beat that price for a helmet that weighs under 300 grams. Good ventilation, easy adjustability by using a little knob on the back, and the straps are nice and soft compared to the Bell and Giro's.
Weaknesses: The pads do not take sweat away -- instead, on hot days, the sweat will sometime drip in your eyes. That said, this only happened to me twice and both days were over 95 degrees. I assume that this would happen with most helmets in super hot and humid conditions.
This is a nice helmet for the price. It has plenty of vents, and it gets good ventilation.
