Features

• Rash guards are compression shirts made from stretchy synthetic materials. They're designed to repel moisture and snap back into shape when pulled.
  
  

Types

• Available in countless styles, colors, and designs, rash guards come sleeveless, with short sleeves, or with long sleeves. Although shorter sleeves are more comfortable, they lack the added protection of the longer-sleeved models that cover the elbows and forearms.
  
  

Benefits

• Aside from the form-fitting skin protection, rash guards get their name for their ability to repel moisture. T-shirts and other clothing can absorb moisture, leading to rashes.
  
  

Considerations

• The stitching on a rash-guard garment should be "flat lock," meaning it sits flat against the fabric. This prevents the seams from rubbing against and irritating skin.
  
  

Warning

• Those who fail to wear a proper rash guard may develop ring worm and other skin infections that are common to grappling sports.
