 HSC (Heat Stress Control)
 Stand 21, a recognized pioneer in heat stress, has developed a new underwear line using virgin materials.
 These fabrics are some of the most breathable in the world thanks to their double-sided formulation.
 Unlike other products, this product keeps the driver cool.
 This is because our underwear works to transfer heat away from your skin, body and the fabric itself.
 This cooling process is achieved thanks to the unique qualities of our materials.
 It is different from other underwear on the market that uses chemical processes (which have limited lasting effects).
 To deliver exceptional performance, the heat generated by the underwear needs to be dissipated outside the racing suit.
 That's why it's important to use a racing suit that is highly breathable.
