Thermo Dry Celliant (TDC) is the first and only clinically proven, smart fiber wetsuit lining. Developed in collaboration with Celliant, who've worked with the likes of Puma and Porsche, TDC is a responsive textile that actively works with its wearer. Its mineral-enhanced, naturally-hydrophobic smart fibers recycle body heat into infrared energy which translates into greater warmth, enhanced endurance, quicker recovery, and improved sporting performance.

About Xcel Thermo Dry Celliant (TDC)

Lance Varon, Xcel Design Director:
"Thermo Dry Celliant is the warmest wetsuit lining ever in over thirty years of Xcel product development. From the moment you put it on, TDC transforms your body into a renewable source of warmth, while improving your ability to achieve peak performance. The results of TDC’s extensive testing far exceeded our expectations, and have redefined what Xcel can achieve in terms of wetsuit warmth and performance. Comparing TDC to other materials, we could literally see and measure the significant increase in warmth. We’re excited to partner with Celliant and to be bringing this groundbreaking technology and its real-world benefits to market. What’s also unique about TDC is that, since the Celliant mineral blend is embedded at the fiber level, TDC technology will never wear off or wash out, so its benefits last for the lifetime of the wetsuit.

David Horinek, Celliant Inventor:
"TDC is an exciting alliance of Xcel’s wetsuit expertise and Celliant’s proven science. The infrared energy delivered by TDC improves circulation and increases tissue oxygen levels, which in turn increase warmth, fend off fatigue, improve stamina, and quicken recovery times in everyone from non-athletes to professionals alike. The cold air and/or water conditions that necessitate a wetsuit are the same conditions in which you’ll benefit from improved circulation and greater tissue oxygen. So for surfers, this means quick and easy access to these performance benefits, simply by putting on their wetsuit.

Mike GleasonXcel Team Athlete:
"I couldn’t believe how warm I was during my first surf in the new Drylock with TDC. Hands down, it’s the warmest suit I’ve ever worn. Plus, after a few very long, very cold East Coast winter sessions, it was amazing to realize how consistently strong and comfortable I felt. It really made a world of difference.”

How Is TDC Made?
TDC’s unique manufacturing process begins with the Celliant mineral blend being ground into a fine powder of particles that are 100 times thinner than a human hair. This powder is then processed into masterbatch (resin) and embedded into the cores of staple fibers. Finally, these fibers are spun into Celliant yarn to create the final TDC smart fiber lining. Because TDC’s active ingredients (Celliant minerals) are embedded at the smart fiber cores, TDC technology will never wear off or wash out, so its benefits last for the lifetime of your wetsuit.
