Thermal Wear

Nasa invented a way of keeping their astronauts at the correct temperature no matter what the atmosphere was like outside the space craft. They did this by using thermal insulation. The tubes that run through the fabric of the clothes worn underneath the suit, have liquid pumped around them to cool them down or heat them up.

This could be adapted into any sportswear keeping the athletes at the perfect temperature that they need to be. After doing a few designs i worked out different of placing the tubes on the body but found that the best way was just straight lines on the bodice and circular points around the legs and arms.
