FLEX 7
The JT Flex 7 is the most comfortable and well made mask today.  Lets first start off with the looks.  Just looking at it makes you want to put it on.  As you notice there is a flexy part of the mask on the bottom.  This is very good for tournaments because when you get shot in the mouth it usually bounces.  If you are worried about it hurting when you get shot there, don't, it doesn't hurt.  The next great thing about the Flex 7 is the thermal lens.  You don't fog up period.  The thing that makes this work is that there are actually 2 lenses.  With an air pocket between the two.  I really don't know the exact physics, but it works.  I have/nor seen a Flex 7 fog.  The only thing that may fog is your glasses(if you wear them).  If you do have glasses, get an X-WIND fan by JT.  It will clear all fog in 10 seconds.  I wear glasses and I don't use the fan due to limited funds, I use 4 dollar a bottle no fog spray.  It works good.  Anyway, back to the mask.  This thing has very comfortable padding and a nice strap that has these little gel lines that feel nice on your head.  It is extremely comfortable and sometimes you can forget you have it on.  The only minus about the mask is that you will have some bare spots left open on your neck and cheeks.  I suggest a neck protector to protect yourself.  It is worth it.  But for the cheek's, be a man.  Overall, I love this mask, and I wouldn't trade it for any other mask in the world.  For around 80 bucks it is pricey, but well worth the money.
