Sustainability at the Core
Each garment in this collection is meticulously crafted in Poland from regenerated nylon derived from ocean plastic and deadstock materials, exemplifying KUST.’s dedication to circular fashion. This endeavour not only breathes new life into discarded resources but also underscores a responsible approach to fashion that harmonises with the environment.
Radek Pestka reflects on the partnership: “Working with KUST. felt entirely organic. We align in our commitment to thoughtful design, conscious production, and an appreciation for timeless pieces that endure.”
Radek’s Creative Vision
Having captivated audiences as the winner of Top Model Poland, Radek Pestka continues to redefine his journey across fashion, music, and digital media. He played a pivotal role in shaping this collection’s vision, from its striking visual identity to the intricacies of the designs.
“I aimed to create swimwear that captures my essence—clean, functional, and lasting,” Radek shares. “Finding the right swimwear has always been a quest: something that fits beautifully, feels exceptional, and looks remarkable. Every detail was finely tuned with KUST., from sourcing sustainable materials to achieving the ideal fit.”
Radek chose a classic black palette, reflecting his wardrobe and a timeless aesthetic. He articulates, “These fitted briefs and relaxed shorts are not just wardrobe staples; they are essentials meant to be worn season after season.”

In an introspective moment, he adds, “This swimwear embodies inclusivity. Like many, I’ve grappled with insecurities, and this project encouraged me to step outside my comfort zone. It was essential to foster self-confidence and comfort for everyone, regardless of where they stand in their journey. Everyone deserves to look and feel incredible in what they wear.”
The RDSLAV X KUST. Swim Capsule is set to launch soon in limited quantities at kust.com and the TFH Warsaw Concept Store, promising to make waves in both style and sustainability.
