Why We Like The Jetstream TT Helmet

The Jetstream TT helmet offers a great combination of speed and safety elements. The polycarbonate material creates a lightweight aerodynamic helmet that also has high impact resistance. Equipped with both MIPS and Koroyd layers, this helmet will reduce impact to the head during a crash.


With five air vents, optimal airflow is created so that you can stay up to speed on race day. A low profile y-strap divider is also in place to help with aerodynamics. The Jetstream also features a magnetic visor for easy removal to switch between two lenses, a basic clear lens and the color enhancing ChromaPop.

Good but....

Thus far I wore the helmet once. It was during an IM 70.3 and it was pouring rain. The fit is nice and aero but the magnet that connects the visor to the helmet is NOT strong enough. It was pouring and my visor was totally fogged up and I couldn't see anything. I was trying to get my fingers in the inside to wipe away the fog and pop, the visor flew off. Totally bummed and devastated. So buyer beware as I don't even see replacement lenses on the site.
