The Smith Jetstream TT MIPS Bike Helmet delivers pure aerodynamic performance for riders who measure success in tenths of a second. This time-trial weapon combines zonal Koroyd® coverage with MIPS technology to keep you protected while you slice through time and space like a two-wheeled missile. The magnetic visor system lets you swap between ChromaPop or clear lenses, while five precisely placed vents allow you to dump heat without creating drag. When the clock is ticking and every watt counts, the Jetstream TT ensures nothing stands between you and that podium finish.

VaporFit™ Dial Adjustment System – Offers 270-degree fit adjustment with the turn of a dial.

Magnetic Visor – Option of ChromaPop™ or clear lenses. ChromaPop™ lenses enhance contrast and natural color to make the details pop.

Ionic+® Antimicrobial Lining – Offers sweat-activated odor control.
