For those who know... this cap is a graphic dedicated to the (hilarious) Cinelli cameo in Ridley Scott's 1991 classic film Thelma and Louise. 

Cinelli's Explorer series caps are a hybrid of the standard 5-panel style cap with the characteristics of classic cycling headwear, entirely handmade in Italy from high density woven PFTE-free water resistant, windproof and breathable organic cotton.
