Louis Garneau Vorttice Helmet:

Time trialists and triathletes take note. The Garneau Vorttice Helmet may be one of the fastest, most advanced helmets we’ve ever encountered for duels with the clock. This is a technological marvel that holds the promise we all look for: the opportunity to buy easy speed.

The front of the Vorttice is dimpled like a golf ball to disturb the airflow just enough to speed its flow over the surface of the helmet. The angled ridges that follow the dimples are vortex generators that compresses air as it flows over the helmet, again speeding its flow down the backside of the helmet. The combination of the two technologies cuts drag by 11 percent.

A single, front vent situated at the point of highest air pressure takes air in and directs it over the head through three different channels to help keep you cool. The Vorttice includes a clear integrated lens to improve airflow around the face. It can be removed or flipped up if desired. Keeping the helmet stable on the head is the Garneau Spiderlock SL which can be adjusted on the fly with just a simple twist of the retention dial. Steplock SL Dividers adjust the length and position of the straps quickly and easily thanks to the locking cam design. And unlike many aero helmets that come with a significant weight penalty, the Vorttice weighs only 340g (12 oz.).

The Garneau Vorttice Helmet comes in two colors -- Grey/white and Red/white. It's available in three sizes from Small through Large.

  • Steplock Divider for quick strap position adjustment
  • Sealed Airdry padding is durable enough to wash and ergonomically designed to optimize comfort
  • Vorticce lens included for the ultimate in aerodynamics
  • Front vents provide excellent cooling across head

Louis Garneau Vorttice Helmet

This TT lid is awesome! It has a nice amount of air flow, and fits great. There is plenty of adjustment with the Spiderlock SL fit system. It can be worn with or without the attachable lens, and Louis Garneau has designed the helmet to be equally aerodynamic either way (unlike some competitor's helmets that depend on the lens). The helmet is also unique in it's design with the cut-off rear. This makes the helmet more aero in cross-winds and if your head is tilted down looking at your computer (or suffering).

Fast Helmet

This TT helmet is fast with and with out the visor. Keeps you cool with the large air vent while still staying aero. With the short tail you can put your head down and be more aero than other TT helmets.

NO Issues

I have had a few TT helmets now. All of them have had a nagging issue. Fit, Visor, Length, Something bugged me. I have worn it as much as any rider and i have had no issues. I even wore it in 100 degree heat and did not notice any over heating issues yes it looks like a golf ball... we're already in spandex It is worth the advantage get it

Highly recommended

The latest in garneau's aero dynamic design. Has a road bike helmet feel to it, which is great for long tt events. Garneau stays true to a great ventilation system with their time trail helmets. Great looking design as well
