Rex Deitesfeld

Born and raised in Colorado, Rex has been skiing almost his entire life. He hit the slopes at the tender age of three and raced competitively for the Lake Eldora Race Team (LERT). During that time, he spent an average of 100 days each year skiing down a snow topped mountain.

After attending the University of Wyoming, Rex launched his professional career at Intec, an industry leader in insulation equipment. At Intec, Rex led product design and operations and eventually became company President, a position he held for 23 years. During his tenure, the company grew from $500,000 to annual revenues of $16 million. Intec was the only manufacturer in the insulation industry that supplied and developed custom products for industry giants like Johns Manville, Guardian Fiberglass, Owens Corning and CertainTeed.

After 31 years, Rex left and reignited his passion for skiing. He quickly recognized the need for advancements in ski boot design and thought he could bring his skills and product innovation to the ski boot market. He immersed himself in new technologies, reached out to industry leaders like Ed Chalmers, who developed the Radial Closure®, and Sven Coomer, the inventor of Zip Fit®. Leveraging this unique combination of talents and experience, Rex co-founded Zay Products in 2011.
