The Trail Adult Helmet is an off-road, all-purpose helmet, with sixteen air-vents for comfort and a lightweight design, perfect for every trail and adventure. When riding off-road, a little extra protection is nice. Just in case you need it, you’ve got some more coverage at the back of your head. You’re just a few clicks away from comfort with the CannonDial. This rotary knob at the back of the helmet makes it easy to dial in the right fit. Its in-mold construction, bonds the polycarbonate outer and foam inner layers of the helmet into one solid piece. It’s how all Cannondale helmets are made. What’s that mean? A stronger, smarter, lighter helmet. Its sturdy fixed visor helps keep the sun and rain out of your eyes – because you never know what the trail, or the sky, will throw at you. Don’t worry about sweating too much. The removable pads can be taken out for drying, washing, or replacing if you want to start fresh.
