Cantide - We appreciate you taking that leap of faith to purchase a product that you had not tried yet and we especially appreciate your review and the constructive feedback.
As far as the lens goes - if you'd like, you can send back your yellow lens with your warranty card and we will send you a dark smoked thermal lens. All of our So Phat Series masks are supposed to come with thermal lenses. Your box must have been packaged incorrectly. The yellow lens is good for low light conditions as it actually brightens things up - it would be good for playing on an overcast day or in the early evening or early morning.
As far as the jawline coverage goes, you might try wearing the mask a little lower on the nose - this helps some people to get more coverage on the jawline as well as increase their field of vision. See the pictures at the end of this thread: http://www.pbnation.com/showthread.php?t=2787493
Thanks again for your time and efforts here in our forum. We truly appreciate your feedback!!
