I bought these pads 3 months ago, I instantly fell in love with them when I tried them on for the first time. They are very responsive to your natural leg movements and they stay in shape, all of my other pads got broken in very fast. I am still in the process of breaking them in. As for specs. The pad is ultra light weight, in my opinion if you are using the right technique for getting up out out the butterfly, a few 100 grams is not going to make much of a difference. The pad is extremely comfortable, good for the long games. One small thing that is a huge pro is the second hole on the butterfly slide. I really under estimated how much that hole is making my butterfly better. I am 6'4", I know that is really tall for a goalie, but I always had trouble getting up from my butterfly because the pad would slide around my leg some, this second hole fixed that problem, so lanky goalie approved. The rebounds are right where I want them to be with these pads, usually if Intake a shot to the knees the bound would go away from where I expected it to go, costing stupid goals. The zero G fixed that problem, I think its that dense foam that they added to the front of the pad, it absorbs all impact. I give it a 5 out of 5 all around except for the pricing. I had to get my custom and Brians charged me $300.00 above retail price.
