About

DIVING UNLIMITED INTERNATIONAL

 

Welcome to DUI! Or, you may know us by our long formal name above. Maybe you’ve known us since the beginning when we started as Skin Diving Unlimited. But if you are just now getting to know us, there is one important thing to remember– UNLIMITED has always been part of our name. That’s because we were founded with the idea of removing limits so you can enjoy your diving experience in warmth and comfort.

An American Success Story

dick_long_aboutSkin Diving Unlimited started in 1963 because our founder, Dick Long, loved to dive. And at 6’2” and 130lbs, he was virtually freezing to death. He opened a dive store 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.

Message from the Founder
Drysuit Diving Around The World

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.

The Authority on Drysuit Diving
Immersed in Comfort
Drysuit Diving is for Everybody
Unlimited Really is Our Middle Name
The World Leader in Drysuits

 

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!

Why Choose DUI?

Here are four key reasons, all reflecting the incredible value you get when you dive DUI:

1. FIT
Nobody can fit you as good as DUI. We have the experience of fitting tens of thousands of divers of all body types and shapes over the years. A DUI drysuit is designed to fit closely while allowing you to wear insulation undergarments and provide you with complete freedom of movement. DUI assures divers an excellent fit no matter what your size. Our drysuits are divided pretty equally into two versions:

  • SELECT SERIES
    33 standard sizes for men & women
    Choose your boot style & size
    Seal choice including ZipSeals
  • SIGNATURE SERIES
    Made-to-measure sizing
    Choose your boot style & size
    Seal choice including ZipSeals
    Even more custom options

    Easy to use even when wearing gloves
  • DUI is constantly conducting Research & Development resulting in numerous inventions and patents. Our latest – BlueHeat Heated DiveWear Insulation – the next evolution in diver comfort.

4. COMMUNITY

Even though we approach every diver’s needs individually, DUI has brought groups of divers together to have fun and explore places wetsuit divers just cannot endure. It starts with the DUI Team – here to help you before, during and long after making your drysuit investment. It extends to more than 400 dive retailers and worldwide distributors. And it culminates with our DUI Owner’s Group (DOGs) who actively gather to travel or meet at one of our annual DEMOTOUR events across the US.
