Of course, the MOST important peice of equipment you can own is your mask. You can play paintball with a $20 pump gun and a handful of paint you picked off the ground, but you absolutely can NOT play without goggles.
That being said, masks should be the nicest, most-cared-for peice of plastic you ever own.
THAT being said, you don't want to waste your time caring for something that's going to fog up on you in the heat of a game, leaves you feeling like your head has twice it's weight, or makes you feel uncomfortable because of flimsiness.
Luckily, the JT Spectra has none, I repeat - NONE, of those symptoms.
Not only are they light, the general comfort of the foam and padding make you seriously check to ensure you're still wearing it. Through 40 degree cold and 90 degree muggy, sweaty weather, these things refused to fog. The only way I've found to make them fog is it to look at the mask and exhale on the lens. Even then, it only fogs for 2 seconds, and that's breathing directly on it. (If you're doing this while playing a game, you're not wearing them correctly. I insist looking at your nearest teammate and copying them.) The plastic is hard enough to protect you from a direct hit, but soft enough to score off a couple bounces. Real easy to communicate through, as well. I had no problems hearing my buddy 20 yards off.
Cleaning them was easy enough once I got home. The sides, bottom, and visor all come off without too much effort (Yes, some effort is needed, I realize this. Would you want a mask that came apart when an acorn hit it?). Rinse them with water and let 'em dry. The goggles? Do the same, just don't use anything abrasive to clean them.
