We call this design the "sweetheart shark" because you can feel the animals innate power as it swims right over your heart. It's made even more dramatic by the black-on-gray design that uses tribal artistry to convey the importance of the shark to native Hawaiians. Like an air conditioner for your skin, these light and breathable shirts let you keep your cool while you pursue an active lifestyle. It's the mix of super-soft pima cotton and moisture-wicking polyester that allows you to workout in these slim fit Ts without being bogged down by heat and perspiration. They're also antimicrobial so you can sweat without ruining the shirt, and feature 50+ UPF protection making it great for hitting the trail or the gym.
