When Smith first introduced Koroyd technology it was a game changer. Fast forward a few years and the Session helmet is still turning heads and providing incredible protection.
Koroyd technology looks a lot like drinking straws clumped together, and while it might not sound innovative, it's a superb material for absorbing impacts. Unlike pure EPS foam, Koroyd evenly distributes forces to better protect your head, plus it's mostly made of air, so you get excellent ventialtion and breathability. By absorbing and crumplinig on impact, the material absorbs energy rather than deflecting it as with traditional foam.
The Session uses Koroyd on startegic parts of the helmet where you are most likely to receive an impact, leaving other areas highly ventilated. This protection is combined with a MIPS liner. MIPS is an internal cradle that effectively reduces rotational forces being passed onto your brain, and has become a standard feature on performance cycling helmets.
Away from the protection, the Session features a highly adjustable retention system, 15 large vents, and an anti-bacterial lining. With three sizes to choose from, getting the right fit has never been easier. The adjustable visor fixes into three separate positions and plays well with goggles and glasses. Finally, it's easily compatible with a camera or light mount.
With the Session, you get the fantastic protective combo of MIPS & Koroyd at an accessible price point. Combined with the excellent quality retention system, this is one for the dedicated mountain biker looking for a top performance lid.
