Man, you guys are good... I picked up the same two details... the thumb welt following the lines of the Nike logo into the thumb strap, and the yellow stitching to match the Nike logo.
Really nice touches on a high end glove... I wish all glove companies paid so much attention to details like that, with the high end gloves they sell in the U.S.
I also noticed, it looks like the use a different color leather (yellow tan) on the inside back of the wrist and back of the finger stalls... really awesome looking glove!
