Hand Down Man Down, or HDMD, is a newly launched clothing line from NBA star and ESPN/ABC personality Mark Jackson. Sales revenue from the collection will support Autism Speaks.

HDMD features long- and short-sleeved shirts, wristbands, headbands and shorts. More products are expected soon. A $1 of every T-shirt sales will be donated to Autism Speaks. Initially, the line will be sold exclusively at HDMDgear.com and will later expand to U.S. retail stores.

Deon Taylor Enterprises is handling a multi-media campaign for HDMD, which will roll out globally during the 2010 NBA playoffs.
