When every second counts.
If you’re at the point where every second counts, an aero helmet might be your next purchase. (Assuming, of course, that you’ve dialed in your aero position and have invested in some speedy wheels.) The days of foregoing an aero helmet in hot weather aren’t completely numbered (Chrissie Wellington never used an aero helmet in her unbeaten Ironman career), but thanks to the innovative venting properties of many of these helmets, you’ll see many triathletes pull one on for even the hottest races.
The name says it all: riders can optimize this helmet for best aerodynamics based on their anatomy, riding position and even course conditions thanks to two different lower tails included with the Selector. There are two small vents that help move air through the helmet to keep you cool. It comes with a removable, vented lens.
The unique dimpled technology on the front of the Vorttice helmet is designed for maximum aerodynamics as it allows air to flow closely to the helmet and then is accelerated to the end of the tail. A unique air intake on the front directs air along your head to three evacuation channels to help keep you cool. The included ventilated lens is designed to improve aerodynamic performance.
Using multiple surface treatments to optimize aerodynamics, the Tardiz has a smooth glass front surface for best airflow and least resistance. Front vents allow for air flow around the head, which then moves through the rear vents. The rear dimpled surface is designed to improve aerodynamics, too. The Aquavent on the top of the helmet allows you to pour water on your head to cool things down in a hurry.

It comes as no surprise that the company that spent so much time making the super-aero Shiv would come up with this drag-reducing aero helmet. There are lots of vents both front and back to channel air by your head, while the retention system allows for one-hand adjustment on the fly.
