Just ordered the Z1 STI. After reading the reviews for the Oxygn and the horrific customer service, even though they're down the street in Denver, I decided to save myself the brain damage and order this helmet. I can tell you the great reviews I read on this helmet are definitly true. The anti-fog coating on this thing is amazing. I can't possibly forsee the face shield coming open in freefall. Only downside: I don't have a huge melon but the X-LRG didn't work even though the sizing chart said it would. Go one size larger. I contacted Para-Gear and they claim that the shell is all one size, it's the liner that changes the fit. I have yet to see if a new liner will fit better but I could live with the X-LRG. Recommendation: Buy It. Too bad my DZ won't let me jump it 'till I have 50 jumps.
