Giro Feature Mountain Bike Helmet- charcoal Clear/ Cyan Lines.  As trail riding progresses, helmets have to evolve. The Feature starts with a new shape that combines a little more coverage than traditional trail helmets, with vents that radiate heat up and out of the helmet; perfect for climbing at lower speeds. And when the trail drops, our rugged In-Form fit system offers one-handed fit and stability adjustment, so you can dial-in the perfect feel and stay focused on the trail ahead.
