The O’Neill Superfreaks to my knowledge, were the first “techy” trunk out on the market. Since then companies such as Volcom, Billabong, Quiksilver, Hurley and RVCA have added their own tech trunks. These tech trunks have helped revolutionize the fabrics we use in board shorts. Tho $10-20 more then your average board short, i’d say its way worth it! Check out sundancebeach.com for their large selection of tech board shorts!
