The Giro Trella MIPS bike helmet offers a comfortable fit with deep coverage and open ventilation in a design that's suitable for everything from swooping singletrack trails to the city streets.

The ease and comfort of our acclaimed Roc Loc Sport MIPS® fit system makes fitting as easy as turning a dial, and the fit system is seamlessly integrated with the Multi-Directional Impact Protection System (MIPS®), which can redirect energy and provide more protection in certain impacts. When you put it all together, you get the versatility you need to ride everything from forested fire-roads to swooping singletrack trails to the city streets.
