How To Measure
Our singlets are sized based on athlete weight. However, athletes who are tall or short for their weight class are recommended to adjust up or down by one size respectively.
Care instructions
Hand wash your singlet with a mild detergent in warm water, leaving the garment to air dry. Do not put the singlet through a machine dryer as the heat can affect the material of the garment.
