We thoroughly reviewed many types of materials for the short sleeve and long sleeve (non-Performance) t-shirts that would display Shark Zen designs. We ultimately chose a perfect blend of cotton and polyester with a premium finish. We were hesitant to include polyester given the stigma around the material being hot and unforgiving. However, this particular blend, along with its quality manufacturing, makes up a product that beats just about any other t-shirt out there on all fronts.

The forty percent polyester fabric adds extra durability for ocean and land activities, as well as repetitive washes. The sixty percent cotton ensures a lightness and breathability that keeps you comfortable in the sun or indoors. The shirts are cut in a stylish, not too snug, not too loose fit, and the overall craftsmanship of the fabric results in one of the softest shirts you've ever felt - if not the softest. When customers first feel a Shark Zen t-shirt, they are always pleasantly surprised.

Occasionally, we may release a color with a slightly different blend of fabric, but the softness, quality, fit, and brand are the same, and the percentage of the blend is always clearly included on the product page for the item.
