Save the earth with sustainable fashion and look amazing doing so! Our swim shorts change color when they get in contact with water! You heard me right, they change color! The fabrics are treated with heat reactive microcapsules that cause the swimming trunks to change colour when they come into contact with cold water! Because the water has a different temperature than the air, the fabric changes color. When the trunks dry and become warmer, the original color will return. * 100% Color Changing * 90% Polyester and 10% Elastane * UPF 50+ protection from the sun's harmful rays * Stretchy * Breathable & Fast-drying * High quality, comfortable mesh liner * Eco friendly and sustainable ||/products/calidays-tshirt
