Giro Phase MTB Helmet

First and foremost, a bike helmet should be cool, comfortable and durable. If you can have all of that without excess weight, you’re onto something good for any kind of ride. The Phase is a great performance value, with the capability to handle daunting climbs and dirt descents. And with the easy fit and adjustability of Roc Loc 5 and the comfort of Super Fit sizing, no wonder it’s so popular.
