Giro Trella MIPS Women's

Our best selling helmets, the Giro Cormick (unisex) and Trella (women's) are very lightweight, very ventilated, highly protective helmets for recreation and transportation riding.

These models combine the more protective extended rear coverage of mountain bike helmets with the increased ventilation and lighter weight of road racing helmets. 

Additionally, the built-in soft visor is much closer to the eyes, which makes is noticeably more effective than the small plastic visor on many bike helmets.

Both helmets are equipped with a MIPS liner and Giro’s Roc Loc 5 system, so the helmet adjusts snugly with a simple turn of a dial.

18 wind tunnel vents with internal channeling provide excellent ventilation.

The Trella is UW sizing (Small/Medium 50cm-57cm).
