Adrian peterson jersey question?

There are sweatshirts that has the mini all over print in the background. The one that ive seen is the chargers sweatshirt with it. its this -Reebok San Diego Chargers Conflict Player Hooded Fleece. just google that and u will see pics. well i was wondering what the logo is in the background of this fleece. i saw a guy with this logo in the background of his Adrian peterson jersey.. i thought it was cool and was hoping to find one. thanks for the help
