Orange-yellow color changing swimshorts
The swimshorts respond to temperature changes. Therefore they need warmth and cold to change color. When the swimshorts are being worn, it is (generally) warm due to body heat and the warmth of the sun. In order to change color, the swimshorts will have to cool down. Water is generally cold so water takes care of it.
Your yellow swimshorts turn into an orange colored pair as soon as you step into the water. Our swimshorts change color when they get in contact with cold water. This isn't because of the moisture, but because of the temperature of the water. As the shorts become dry the first color reveals again.
Read here about the technical details of the color changing effect.
*NOTE. You will receive this pair in the orange colored form because we cannot deliver 'warm' swimshorts. Once you start wearing them, they will become a solid yellow color.
