This t-shirt for scuba divers takes on the familiar March of Progress image originally published in 1965 to show the progression of 25 million years of human evolution. Typically, the illustration shows a primate walking on all fours progressing to an ape-like figure walking upright, and each subsequent image shows a figure that looks more and more like homo sapiens.
In this case, the final two images in the progression depict scuba divers in silhouette form. The last image is of a scuba diver horizontal in the water, which is preceded by the silhouette of a diver performing a giant stride water entry.
This all-white silhouette design looks great on a black tee, as shown here, or get this in a variety of different color options. This top can be purchased in a comfortable unisex cut as shown, or get a cut for women or youth.
