Xen Mountain Bike Helmet is the original and now iconic all-mountain helmet. Its
smooth low-profile style hints at skate-style influence, but its big vents,
light weight, and expanded rear coverage define it as a high performance helmet
for the modern mountain biker. And the colors and graphics make the Xen truly
In-mold construction fuses a tough polycarbonate outer shell with the helmet’s
impact-absorbing foam liner. The fusion process allows Giro to sculpt better
ventilation systems, so In-mold helmets can be lighter and cooler than
Ventilation - Giro
helmets are developed utilizing Giro’s proprietary Wind Tunnel™ ventilation
system, which combines active vents with internal exhaust channels that thrust
cool, fresh air over and around the riders head-while forcing heat and stale air
out. This significant increase in air channeling makes a difference that riders
will immediately feel and appreciate.
Roc Loc 4
- This system, found exclusively on the Xen, offers full adjustment of both fit
tension and vertical position. Roc Loc 4 allows riders to easily customize fit,
making the helmet more stable, especially on rough terrain.
- Point Of View visors are anchored by a patented internal clutch mechanism that
allows 15-degrees of tool-free, on-the-fly vertical adjustment while preventing
the visor from rattling and coming loose over rough and technical terrain.
- Roll Cage reinforcement is a tough web of DuPont ® Nylon® molded inside a
helmet’s EPS foam liner. It provides an extra measure of strength and integrity
that you’ll never notice…unless you need it.
