e3: exertion euphoric effects #serotonin

Serotonin is one of the naturally occurring molecules created in our body, and provides a natural mood boost when we're doing activities we like, especially those involving exertion. That feeling of euphoria known as a "runner's high" after an intense workout is down to a surge in serotonin (and other naturally occurring molecules). Its simple little molecular shape is represented in the design and each carbon and nitrogen atom is replaced by a classic 1990s smiley. 

This e3 collection is specific to the contrast coloured Varsity Hoodie, perhaps the perfect sporty garment to pull on after a race, match, training session, or any activity for that matter.
