Sometimes the simplest designs are the smartest. The Trinity offers classic design and an adjustable fit at a great price.
Sometimes the simplest designs are also the smartest. The Trinity™ is an easy fit for riders who want a classic cycling helmet that doesn’t compromise comfort or performance. It includes key features like In-Mold construction to keep the weight low, and the easy one-handed adjustments of our acclaimed Acu Dial™ system for a quick, sure fit no matter where or how far you ride.
Acu-Dial The Acu Dial system combines single-handed adjustment with a full fit band that brings a quick, sure, ponytail-compatible fit in Giro's line of Universal Fit helmets.
In-Mold Construction 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 traditional helmets.
Giro has been supplying quality light-weight cycling helmets to millions of riders, cyclists, skiers and snowboarders around the world since 1985. Giro is the Helmet of choice for winners of mountain bike world championships, cyclocross world championships, Triathlon and Iron Man world championships.
