Giro Source MIPS Helmet


Add Protect+ Powered by Extend™

Why We Like The Source MIPS Helmet

When out riding our favorite trails, knowing that our noggins are protected in case we go rubber side up lets us ride with even more freedom. The Giro Source MIPS is a new trail-ready helmet, built with MIPS for a layer that disperses rotational forces upon impact and an adjustable visor to better protect against the glare of the sun. 17 vents help pull air through the helmet, so you can stay cool as you hammer up your favorite climb.
  • Giro's latest trail-ready helmet
  • MIPS layer helps disperse rotational impacts
  • 17 vents keep your head cool on warm days
  • Roc Loc 5 adjustment hones in the fit for best comfort

Great looking helmet with good coverage

This helmet fits well: it wraps around my head nicely rather than just sitting on top (like the Smith Forefront). The Roc Loc system is super comfortable. The helmet sits lower towards the ears, and has longer coverage in the back. And it’s surprisingly super lightweight. The only con is that it may not be as ventilated as some other helmets.

Is there any room for a pony tail in the back and how comfortable is it to wear sunglasses if it sits low on your ears?
