Seller's description

Funny dinosaur physics equation. Perfect for geeks who love science (and Dinosaurs).

This makes for a great staple t-shirt. It's made of a thicker, heavier cotton, but it's still soft. And the double stitching on the neckline and sleeves add more durability to what is sure to be a favorite!

• 100% ringspun cotton
• 4.5 oz (153 g/m2)
• Pre-shrunk
• Shoulder-to-shoulder taping
• Quarter-turned to avoid crease down the center

I bought this shirt for my teenage son, and then my husband wanted one of his own. So, I got him his own. I am saving it for his birthday.
