You better be a stud player if you wear these. The price is for one treDCAL to give you the option of what you want to wear on the other pad. These are not recommended to be worn under navy blue or black pants.
Made of a closed cell foam similar to that used in thigh pads so they can be used in any game condition. Although they were originally made for thigh pads, treDCALs can stick the plastic of hard shell girdles and other foam rubber materials. Unfortunately, they are not meant to stick to fabric. treDCALs work best under lighter colored clothing but they do work under darking colored clothing by showing the outlines of the image.
