Notes. If hot spots or discomfort are experienced, try rearranging the pad system to accommodate a more comfortable fit. If discomfort persists, try resizing the shell.See the sizing and fitting troubleshooting guidelines (chapter 2) for problems with fit, such as tightness or looseness, or if the helmet profile is too high or too low.When trying on the helmet for the first time in a cold environment, wear the helmet for a few minutes to allow the pads to warm up and conform to the shape of the head.
