Father-son duo Martin Negron Jr. and Sr. pitched their hockey apparel and gear brand, Duzter, on Shark Tank Season 16. The company is known for selling high-quality hockey gear to help players feel more comfortable on the ice.
Martin Jr., a 14U hockey player, needed comfortable layer compression with cut resistant fabric clothing but couldn’t find the right fit, so he decided to create his own. With his father’s help, he founded Duzter, a sporting goods brand for hockey players.
They currently sell compression pants, shirts, shorts, and hoodies on their official website and in select stores across Maryland, Colorado, Nevada, Pennsylvania, and the UK.

Who Is The Founder Of Duzter?
Duzter, an ice hockey clothing and gear company, was founded in 2022 by father-son duo Martin Negron Jr. and Sr.
With 25 years of experience in production, quality control, and manufacturing, Martin Sr. helped his son launch a company focused on comfortable compression clothing for hockey players.
How Was The Shark Tank Pitch Of Duzter?
Martin Negron Jr. and Sr. entered Shark Tank seeking $200,000 in exchange for 10% equity in their company, valuing it at $2 million. They presented their cut-resistant protective clothing and demonstrated how it protects the body even when struck by a skate-sharpening knife. Their product uses A5 cut protection.
Martin Sr. designed the product and currently holds three patents that protect its design. When Kevin O’Leary asked about sales, Martin Sr. revealed that in less than two years, they had generated $326,000 in lifetime sales through D2C and retail channels in 2024. The cost to produce a young player’s shirt is $26, and it sells for $85.
Daymond John felt the business was too technical for him to assist with manufacturing, so he opted out. Kevin O’Leary believed competing with the three big players in the hockey equipment market would be challenging. He suggested a licensing deal as a better option but ultimately declined to invest. Guest Shark Rashaun Williams also passed, saying he couldn’t add enough value to the business.
Lori Greiner agreed that a licensing deal with a major player was a smart approach but still chose not to invest. Mark Cuban, however, offered $200,000 for 20% equity, making it clear that this was his final offer. Martin Negron Jr. and Sr. accepted the deal.

Duzter Shark Tank Update
This father-son team successfully pitched their business on Shark Tank and convinced Mark Cuban to invest.
Moving forward, their plan could be to grow as an independent brand. However, if they face challenges, they may consider a licensing deal as an alternative.
Additionally, they are offering custom-designed compression clothing with team logos and branding, made with a comfortable layered fabric that includes cut-resistant protection.
What Is the Net Worth of Duzter?
The hockey equipment market is highly competitive, with only three major companies dominating the industry. Even big brands like Nike have struggled to break into this space.
Previously, this company raised funding at a $1 million valuation. Assuming an annual growth rate of 5.8%, its estimated net worth could now be around $1.2 million.
