Montirex marks sixth birthday milestone with major discounts

Liverpool-founded sportswear brand Montirex is celebrating a major milestone ahead of its sixth anniversary on 1st May, announcing a staggering £76.7 million turnover.

What began as a lockdown project in co-founder Kieran Riddell-Austin’s home has become one of the fastest-growing sportswear brands in the UK and Ireland. Created by best mates Kieran and Daniel Yuen, Montirex quickly developed a loyal customer base drawn to its performance-led streetwear designs.

That early success caught the attention of high-street heavyweights JD Sports and Footasylum, helping the brand expand its reach across the UK. In September 2024, Montirex hit another major milestone with the launch of its first physical store—a huge step for a business that started with just an online presence and big ambitions.

As it celebrates six years of growth and graft, Montirex is giving back to the customers who helped make it happen. This Friday (3rd May), the brand is running a six-hour site-wide sale, offering 15% off everything on its website from 9am to 3pm.

Montirex co-founder Kieran Riddell-Austin said:

“We’re hugely grateful to our loyal customers who’ve backed our vision and supported us on this incredible journey so far. Montirex simply wouldn’t have grown so quickly without their support. We are looking forward to celebrating with our customers on Friday who can enjoy a site-wide discount.”

With a rapidly growing fanbase, landmark partnerships, and a flagship store now open, Montirex is showing no signs of slowing down. What started in a bedroom in Liverpool has grown into a powerhouse brand—proving once again that big things can come from humble beginnings.
