Wiggle.com Fox Mainframe Helmet Strap Causes Distraction While Riding

I opted for the Fox Mainframe Helmet MIPS from Wiggle.com, helmet strap makes red lines under my chin every time I wear it, have to ride most of the trip uncomfortably, the problem still exists after several attempts to fix the strap. after a while that I often have to stop and adjust it again, it's not hard to adjust the strap on the trail, but having to do it all the time is annoying and makes me not enjoy my ride as much. It’s harder for me to focus on the road, also makes riding less fun overall. tried making a bunch of changes to make it fit better, but nothing works, know that not all gear works well for everyone, but the constant annoyance and distraction are not just small problems. They make riding less fun and less safe for me.
