TDP Gear! Hats and T-shirts.... We're now offering licensed hats, T-shirts and possibly other products sporting GM trademarked logos. These are high quality products that were previously available only through GM or during their Chevrolet/GMC promotional tours. These cotton T-shirts are made by Fruit of the Loom, and are available in large or XL ($15 each). The high quality black and stone colored hats are all cloth with an adjustable Velcro strap, and with an embroidered Duramax Diesel logo (hats & t-shirts sold separately - $15 each).
