The foam padding is very thick and very soft making it fit many different facial shapes easily. This also means that you can easily adjust the strap to hold it tightly to your face without causing discomfort. There is addition foam by your ear for added comfort. There's a slot in the foam for those that wear glasses. There is also a lot of space between you face and the lens allowing room for you glasses. I don't wear glasses so this mask is not as low profile as it could be but the high protection makes it worth it. Speaking of which i am stunned when i hear of people swallowing paintballs or getting their lip busted and so on, at the very worst i might taste a little paint, but i've never had a paintball come in contact with any part of my face, forehead etc and i don't ever use the visor. The lens changing system is nearly flawless, once you get used to it you can easily swap lenses in under a minute. I can dissassemble the whole mask in probably a minute and a half, very quick and easy. The visibility is the best i've ever experienced. The thermal lenses will not fog at all IF they are sealed, but see my comment about this below.
Well this mask is not light, if weight is the most important thing to you then try the i3. All the little gills and holes in the mask are almost impossible to clean. I use a toothbrush and i still can't get most of it out, so if you want to keep it clean then run it under water the same day you play, do not wait or it won't come out!! Can't forget about the fan, the only thing the fan does is weigh down the mask more than it already is. If you are dripping with sweat you might feel a slight although uneven breeze across your forehead but that's it. I've never used other fans so maybe this is normal. Also once you install the fan into your mask you'll be luck to get it out with out snapping the tab that holds it in. Fortunately it fits so snugly that it seems like you don't need that tab for it to stay in place but i haven't tried playing with it installed since i broke the tab. Although i don't plan on ever using it again.... and then the lens.......
Last but not least is the stupid proto lenses. First off do not touch the inner pane with anything but nice soft cloth because it scratches very easily. Secondly before you use the lens go to your local dollar store and buy the cheap runny superglue and run a very light amount around the foam that holds the thin inner pain to the outer pain. DO NOT let the super glue touch any part of the lens you wish to see through because it ruins the finish. The reason you must do this is because the adhesive that proto uses falls apart once it comes in contact with water so the inner lens will pull away from the outer lens. I actually had a tiny spider crawl in between the two lenses while i was playing, very very distracting, lol. However as i said above before water separates the lens it works great but after you seal it up with superglue the lens works even better (assuming you seal it completely). I have not had it fog since July and i play at least once a week in southern ny, so it ranges from 98 and 90% humidity to 30 degrees and snow.
considering how comfortable it is the weight isn't an issue and if you clean it the same day you play you won't have a problem there. The only other thing is sealing up the lens (read above) but all in all for 50 or 60 bucks this mask is well worth the money!
