Giro Feature Mountain Bicycle Helmet. All trails, all the time is what the Giro Feature Mountain Bicycle Helmet is all about. The Feature boasts a low profile shape with more coverage than traditional XC helmets, yet maintains a sleek and slim profile. Strategically placed vents radiate heat up and out when you're climbing at lower speeds and the single piece In Mold shell increases durability while keeping weight to a minimum. When you're ready to drop in, the rugged In Form retention system provides one handed fit and stability adjustment so you can dial in the feel and focus on the trail ahead. If you prefer bikes with 5 6 of suspension and on occasion sport body armor you've found your perfect Bicycle Helmet.
