I recently bought this mask as a local shop and after hearing the only good things about it, decided to try it on. I was sold. I am 6'8", 275 lbs...this fits almost perfectly. No complaints whatsoever other than my chin does stick out a little.
The vision within this mask is superb. I had no trouble seeing everything on the field. Had no fogging, no glares...everything went as I would hoped. Dye makes fantastic products.
The weight is almost nothing. I forget it is on my face sometimes.
It is eincredibly easy to change out lenses which is a huge step up form the i3 pro. Vfofrce had this dialed in as does Dye now.
Conclusion:
I would highly recommen this mask to anyone looking to have quality and assurance between them and paint. Try it on first though. They certainly aren't made for everyone.
