This T-shirt, available in short and long sleeves, is made from premium stretch fabric with UPF 50+ UV protection. It's ideal for protecting swimmers from wind, sun, jellyfish stings, and abrasions or cuts from the seabed. Its pattern, based on large panels, and the seams reduced to a minimum, optimize the natural elasticity of the fabric and prevent annoying chafing. All seams have been made with flat seams with anti-chafing thread. It is also an ideal garment to use as an interior of the diving suit. Its high neck prevents the usual neoprene neck chafing when diving intensively for a long period of time.
