Cutting-Edge Protection
Crashing. It’s a part of the mountain biking life. It’s how you get better at riding. But the A1 MIPS Classic Helmet ensures your head is kept safe when your skills and grip levels let you down. Firstly, a durable polycarbonate shell gives you a lid that is up to the daily knocks of mountain biking. This tough shell is in-moulded to an impact-absorbing liner. Extending down both the sides and back of the head, the extra coverage provides protection no matter which way you crash. Cutting edge MIPS brain protection system can also be found, boosting safety still further.
MIPS (Multi-directional Impact Protection System)
The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.
Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.
Trail Riding Comfort
When you’re riding you’ll also revel in the comfort of the A1. a total of 16 air vents, 8 to the front and 8 to the rear, keeps airflow turbocharged over your head. Cool air rushes in. Warm moist air rushes out. Perfect. The soft, quick-wicking liner also contributes greatly to your comfort levels. Sweat is soon dealt with, moving it away from your scalp while the anti-microbial performance prevents itching and odours. It’s washable too, so you can also feel fresh every time you go ride.
