The Smith Jetstream TT Mips® Road Bike Helmet is for riders looking to focus on aerodynamics and make sure every second of speed goes unaccounted for. This helmet is specialized for time-trials and riders looking for durable, lightweight comfort and performance. The fusion of Zonal KOROYD® and MIPS® creates the best source of coverage and protection from impacts caused by great momentum. It features VaporFit dial that provides 270-degree fitting as well as a low-profile Y-strap divider that'll reduce wind noise and aerodynamic drag.
