The Louis Garneau P-09 Helmet marks the next generation of time trial helmet. This truly revolutionary aerodynamic helmet is developed with Alphamantis, designed from the ground up to be faster than the competition. The P-09 Helmet takes the innovative technology of Louis Garneau's Vorttice helmet and updates it with improved aerodynamics, improved ventilation, and an improved lens system all in search of a more efficient, more comfortable helmet.

A texturizing effect over the reduced frontal area extends towards the back of the helmet for better laminal airflow. The P-09 features large vents to gulp in air, directing it through the helmet via the Internal Evacuation Channel and out the inverted tail for more breathable helmet. Inside, the Spiderlock® Pro TT keeps the helmet stable and comfortable with its highly adjustable system, while the Pro-lock straps offer secure adjustment for a great fitting aero helmet.

The Louis Garneau P-09 Helmet includes the P-09 Smoke 7F7 lens. Claimed weight: 350 grams.

Overall Rating
This product has given me renewed motivation to get out and ride

I like that this helmet weighs less than my old non aero helmet. I get less wind noise even though going faster. One of my concerns was that it would be too hot in warmer weather. This has not been the case. For my usual time on the bike 1 to 2 hours the recent 80 degree temperatures have not been a problem. Maybe because I am moving so much faster now, lol.

I settle into the aero position and just keep accelerating. Before I know it there are no more gears on my Compact gear set. Time to replace the chain and get bigger chain rings.

My only issue so far is that my big head is pushing my ears against the flexible ear flaps, which can become irritating. I deal with this by wedging the ear flaps open about a 116 with a piece of rubber foam.
