DAKINE emerged from Maui, Hawaii making surfing accessories including board bags and leashes in 1979. Since then, their product line has expanded to other extreme sports including skate, bike, and kite surfing. Within Dakine’s accessory lineup is this trucker snapback cap featuring a chin strap. My guess is that it is for those who wanna rock headwear while doing something extreme but don’t want to lose their cap. Check it out on www.amazon.com.
