Skin Diving Unlimited started in 1963 because our founder, Dick Long, loved to dive. And at 6’2” and 130lbs, he was always freezing. He opened a dive shop in San Diego with $1500 and an old air compressor and started making custom wetsuits. Through his innovative designs and techniques, he quickly garnered a reputation as “The Guy” to help keep divers warm.

In the late 60’s, DUI invented hot water suits and systems for commercial and military divers. This allowed divers to go to deeper depths and for longer periods than ever believed possible. DUI’s designs were used in the frigid waters of the North Sea for the Offshore Oil Industry and in SeaLab I & II. And divers welcomed the Apollo astronauts back to earth wearing their custom designed DUI wetsuits.Our heart has always belonged to the recreational diver because we love diving, too. So we decided to use the expertise we developed with commercial and military divers to help recreational divers improve their underwater experience. How could we help sport divers dive more often and in more comfort? This began our current obsession with fit, quality materials, impeccable workmanship and new innovations.

Perhaps the best reflection of our company journey and our dedication to improving diver comfort is demonstrated in our slogans used over the years…

That last statement is thanks to the tens of thousands of divers who became avid DUI divers – from commercial and military to technical and police/fire/public safety to weekend warriors. You are all why we do what we do. 50 years later…we’re just getting warmed up!
