Couldn't wait to get this mask. I was sorely disappointed after trying it on with my other gear. They use velcro to close the mask in the back, which is all well and good. However, the "hook" side of the velcro is on the wrong side. You should be able to close the mask as far as you need to and then the remaining velcro strips that are still showing would be the "loop" side of the velcro. But it's not. As a result when you wear your hat and/or your goggles, the material from either of those items gets stuck in the "hooks" of the velcro-basically ripping the hat or goggle strap in the process. I had a pair of $150 Electric goggles get stuck on the velcro and was not a happy guy when it started to shred the strap. It would be a good mask if they switched up the velcro or changed the design of how it closed. For now, just buy a cheaper alternative and cut a small hole in it. Guaranteed to be less headaches.
