The world’s fastest-wicking fiber
4DG™ Fiber
   In socks…

                     where it can
                     evaporate.


Moisture is wicked
 out of the shoe
Why are dry socks important?

     Dry socks are cooler in the heat.

     Dry socks are warmer in the cold.

     Dry socks are more comfortable.

     Dry socks reduce rubbing friction,
     preventing abrasion and reducing
     injury.

imply favorable results.
Is 4DG™ fiber really that much better?
Test 1: Moisture extraction

                              Test socks: “liner” socks
