Jay-Z and his business partners certainly know how to rustle up some cash when it's needed, and that's exactly what they're doing with a new, ultra-exclusive line of denim for Rocawear. 'The Jay-Z Private Reserve Denim Collection' is a direct benefit for victims of the catastrophic earthquake in Haiti that took place in January 2010. While there were record-breaking donations shortly after the tragedy, it's more important than ever to pump money into the country to rebuild its infrastructure and maintain security.

The collection consists of 90 pieces of Japanese-made denim with a button fly closure, 5-pocket style and contrast topstitching. There are three different styles of jeans in all in a light blue, dark blue and black. The line, only available through Rocawear's website, ranges in price between $225-$275. All sales go straight to Hope For Haiti -- a non-profit that specifically focuses on children in Haiti by improving education, nutrition and healthcare.

Hov's charitable collection is yet another savvy move in an attempt to make Rocawear more contemporary and adaptable to modern fashion trends. Jay recently celebrated the label's new line by co-hosting a lavish party with GQ that celebrated the incorporation of more high fashion concepts into the popular streetwear line.
