Freelance Activewear Designer
Designing Activewear and Sportswear for over 20 years
Activewear Design Services
As a freelance sports and activewear designer, I create performance-driven apparel that fuses technical innovation with modern, fashion-led aesthetics. My work covers gymwear, yoga collections, cycling kits, golfwear, running apparel, boxing apparel, teamwear and wellness wear, designed for movement, durability, and market appeal.
With over 20 years of experience, I’ve led global activewear collections for brands like Umbro and spent five years designing technical sportswear at Puma’s European HQ. My activewear portfolio includes gymwear for Dare2b, outdoor clothing for Next, equestrianwear for Equidae London, golfwear for Reflo, and startup capsule collections across the UK and Europe.
I’ve also developed runningwear for Mokimor, combat apparel for Fly Sports and Box-Up Nation, and athleisure ranges for creator-led brands. Most recently, I’ve delivered collections for performance teams including Maserati MSG, Envision Racing, and Sky Tempesta, combining trend insight with engineering-led garment design.
My services cover the full product development cycle: from creative direction and trend research, through to CAD sketches, tech packs, fabric selection and sampling. Whether you’re launching a new fitnesswear brand or scaling an existing label, I tailor every project to meet your brand’s goals, audience and market strategy.

Once your designs are approved, I can help you move into sourcing and sampling—whether you need gymwear, yoga apparel, team kits, or athleisure lines. Professionally prepared files ensure you’re production-ready and able to approach suppliers confidently.

Clothing That Works in the Gym and On the Streets
Technical Activewear Designer Blending Function with Fashion
My approach to activewear and athleisure design blends style with function. I bring a streetwear sensibility into my sportswear work—creating clothing that performs technically but still feels fashion-forward. The challenge of combining movement, comfort, and trend awareness is what drives my creativity.
This connection runs deep. Growing up immersed in football, outdoor sports, and subculture, I developed a real-world understanding of the clothing people wear and why it matters. Whether it’s a technical base layer, oversized hoodie or a compression short—good activewear must feel intuitive and wearable.
I focus on the critical details that elevate a collection: fabric performance, functional trims, logo placement, and ease of movement. My designs aim to meet the needs of both athletes and trend-conscious consumers—ensuring that your activewear collection stands out in the studio, on the pitch, or on the street.
