This unisex triathlon shirt celebrates endurance athletes with a heartbeat design that speaks to the sport's spirit. Made from substantial 100% ring-spun cotton (or a cotton-poly blend depending on color), it's soft yet durable enough for everyday wear, with double stitching reinforcing the neckline and sleeves. The pre-shrunk fabric and shoulder-to-shoulder taping ensure this becomes a reliable staple in your wardrobe.
