Made for urban cyclists and recreational road riders, the Smith Portal MIPS bike helmet combines an easy-to-customize fit with MIPS technology that reduces trauma in the event of an angled impact.
- Rotational motion can cause brain injuries; with MIPS, a low-friction layer slides 10 to 15mm in all directions, reducing rotational motion to the brain during impact
- Lightweight in-mold construction results in a strong yet lightweight helmet that deforms upon impact, absorbing energy and protecting your head
- VaporFit adjustable fit system and 18 optimized vents combine aerodynamic performance and cooling airflow
- AirEvac Ventilation system vents warm, moist air away from your sunglasses to boost distortion-free vision
- XT2 antimicrobial performance lining inhibits the buildup of odor-causing bacteria
- Certifications: CPSC, CE EN 1078, AS/NZS2063
To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
