The UK activewear market is booming. Here's how UK brand owners are sourcing high-quality gymwear and sportswear from China — and building brands that can compete.
In summary: The UK activewear market is worth over £6 billion and growing. UK brand owners can source high-quality leggings, sports bras, tops, and performance accessories from manufacturers in China — particularly in Fujian, Guangdong, and Zhejiang provinces. Key considerations include fabric quality and composition testing, MOQs (typically 100–500 units per style for private label), UK import duty at 12% for most clothing categories, and textile labelling compliance. Working with a sourcing agent significantly reduces quality risk and speeds up the factory selection process.
Picture the scene: it's 7am on a Monday morning. Half of Britain is apparently in a gym. The other half is wearing activewear to the office and calling it "athleisure." And somewhere in a factory in Fujian Province, China, the leggings they're both wearing were made for approximately one-eighth of the retail price.
I've always found the activewear market fascinating. It's one of those categories where the gap between the cost of manufacturing and the retail price is genuinely eye-opening — and where strong branding, quality materials, and smart sourcing can build a highly profitable business. The UK activewear market cleared £6 billion in 2024 and continues to grow, driven by a culture shift around health, wellness, and the happy blurring of gym wear and everyday life.
At Epic Sourcing UK, we help British entrepreneurs and brand owners source activewear and sportswear from China. It's one of the most popular categories we work with, and also one where I see the most mistakes made by first-timers. So without further ado, let me walk you through how to do it properly.
China dominates global activewear manufacturing. The country's textile manufacturing clusters — particularly Fujian (famous for sportswear), Guangdong, and Zhejiang — produce everything from mass-market basics to premium performance gear for global brands. Here's what's available to UK buyers:
Gymwear and leggings: The biggest category. High-waist leggings, shorts, bike shorts, and cycling tights. Chinese manufacturers have mastered performance fabrics including nylon-spandex blends, polyester-elastane, and seamless knit constructions. Quality is genuinely excellent at the right price point when you source from the right factory.
Sports tops and bras: Compression tops, tank tops, crop tops, and sports bras. Seamless manufacturing technology — using circular knitting machines — has transformed this category. The quality achievable at a competitive landed cost is remarkable compared to European manufacturing.
Outerwear and tracksuits: Windbreakers, hoodies, zip-ups, and full tracksuit sets. Popular with both individual brand owners and team kit suppliers targeting football clubs and school sports programmes.
Performance accessories: Resistance bands, gym bags, water bottles, yoga mats, and grip socks. These are often bundled with apparel lines to build a full-range brand identity and increase average order value.
Specialist sportswear: Cycling kit, triathlon suits, swimming gear, and martial arts clothing. More specialist manufacturing capability, typically higher MOQs, but significant margin opportunity in niche categories with loyal buyer communities.
One of our UK clients launched a women's gymwear brand targeting the 35+ age group — a segment they felt was underserved by the major players. They started with three private label styles sourced through our Fujian factory network and built a six-figure Shopify store within the first year. The brand identity was entirely theirs; the manufacturing capability was entirely China's.
Quality control is the defining challenge in activewear sourcing. You can find hundreds of factories on Alibaba claiming to produce premium sportswear — and many of them genuinely do. But there are also plenty that cut corners on fabric weight, stitching, and print quality, resulting in leggings that go see-through when you squat or prints that crack after three washes.
Look in the right regions. Fujian Province (particularly Quanzhou and Xiamen) is the heart of China's sportswear manufacturing industry. Guangzhou and the Pearl River Delta are also strong. Factories in these regions have deep experience with international buyers and the quality expectations of Western markets — it's worth targeting your search here specifically.
Use Alibaba carefully. Filter for Verified Suppliers with trade assurance and third-party audits. Request a product range catalogue and, critically, ask about their fabric suppliers. The best activewear factories work with premium fabric mills and will happily tell you which ones. Read our guide on the role of sourcing agents in China to understand whether professional sourcing support makes sense for your situation.
Use a sourcing agent. For activewear specifically, we'd argue this is close to essential for first-time buyers. The technical specifications — fabric composition, weight (gsm), stretch recovery, colour fastness — require expertise to specify and inspect correctly. At Epic, we do this as part of our Private Label Package.
Sourcing Hack #1: When evaluating activewear factories, always ask for fabric composition certifications and test reports. Premium factories will have OEKO-TEX Standard 100 or equivalent certifications for their fabrics, confirming they're free from harmful substances. This matters for UK consumer safety compliance and is a genuine quality signal — it separates factories that take quality seriously from those that don't.
The UK has specific labelling and safety requirements for clothing sold domestically, and these apply whether you're manufacturing in Manchester or Guangzhou. Getting this wrong costs you money and damages your brand's reputation with customers.
Textile labelling regulations: Under the UK Textile Products (Labelling and Fibre Composition) Regulations 2012, all textile products sold in the UK must have care labels showing fibre composition (in English), country of origin, and care instructions. Your Chinese manufacturer should produce care labels to your specification — insist on this before production begins, not after.
REACH regulations: UK-retained REACH regulations restrict hazardous chemicals in textile products, including certain azo dyes, formaldehyde residues, and heavy metals in dyes. Reputable Chinese manufacturers will have test reports demonstrating compliance — always request these before committing to a supplier.
Product safety: The UK's General Product Safety Regulations apply to clothing. For activewear, this includes ensuring any drawstrings, cords, or attachments don't pose an entanglement hazard. Specific and stricter standards apply for children's clothing.
Sizing accuracy: There's no mandatory UK sizing standard, but consumer expectations are well-established. Ensure your factory clearly understands UK sizing (and the differences between UK, EU, and US sizing charts) — mislabelled sizing is one of the most common causes of returns for imported clothing brands. Read our complete guide to importing from China to the UK for a full compliance overview.
Sourcing Hack #2: Always order a size run sample set — at minimum XS through XL — before committing to a production order. Activewear sizing inconsistency is a well-known issue in Chinese manufacturing, and you want to physically test and measure every size against your intended UK sizing chart before production begins. This step alone prevents enormous post-delivery headaches.
MOQs vary significantly depending on the product type, the level of customisation, and the factory you're working with. Here's a rough guide based on our experience at Epic:
White label activewear (existing styles, your branding): MOQs can be as low as 50–100 pieces per style in some factories, though 200+ is more typical. Our White Label Package is designed for brands that want to launch without large inventory commitments while still having branded product to sell.
Private label activewear (custom colours, fabrics, or design modifications): Typically 200–500 pieces per style. This is the sweet spot for most UK activewear brands — enough customisation to genuinely differentiate, manageable MOQs. See our Private Label Package for how we structure this with UK brand owners.
Fully custom / OEM manufacturing: New designs from scratch, custom fabric development, proprietary construction. MOQs of 500–1,000+ pieces per style, plus development costs. This is the route for established brands looking to build a truly defensible product range. Our Secret Label Package offers complete supply chain confidentiality for brands at this stage. For more on the OEM approach, read our post on unlocking the power of OEM for small businesses.
Sourcing Hack #3: Many UK activewear brands launch successfully with a mixed approach — white label basics (leggings, sports bras in classic black) combined with 2–3 private label hero pieces in a signature colour or design. This keeps total upfront investment manageable while giving you genuinely differentiated products to lead with in your marketing. It's a strategy we often recommend to new brand owners starting with limited capital.
Activewear is a category where landed cost calculations really matter, because UK import duty on clothing is relatively high compared to many other product categories. Here's a breakdown of what you're actually paying:
Factory price: Leggings typically run from USD $4–$12 per unit depending on fabric quality and customisation. Sports bras range from $3–$9. Tracksuits, $10–$25. These prices are FOB (Free On Board) — i.e., cost to the export port in China.
Sea freight: A 20ft container from China to Felixstowe typically costs £1,500–£3,000 at current rates. Most activewear brands starting out use LCL (Less than Container Load) consolidation for smaller orders, which runs approximately £150–£400 per cubic metre.
UK Import Duty: Here's the important bit: most clothing attracts 12% import duty in the UK, based on the customs value (factory price + freight + insurance). This is notably higher than many other product categories, so factor it in carefully when running your margin calculations before committing to a product range.
Import VAT: 20% on the full customs value (including duty). If you're VAT registered, you'll reclaim this. If you're not, plan accordingly and price it into your retail calculation from the start.
Customs clearance: Budget £150–£300 per shipment for customs clearance agent fees.
Sourcing Hack #4: Before signing off on a product range, build a full landed cost model: factory price + freight + 12% duty + VAT (if non-recoverable) + clearance fees. Then apply your desired gross margin — typically 50–60% for DTC activewear brands — to arrive at your retail price. If the numbers don't work at the factory price you've been quoted, push back on the factory price before assuming the business case doesn't stack up. Read our post on how small businesses can cut costs by sourcing directly for practical margin optimisation tips.
The UK activewear market is competitive — but it's also full of brands that win on aesthetics, community, and values rather than price. Competing on price alone against the Amazons of the world is a losing strategy. Here's the approach we recommend to UK activewear brand owners building something sustainable:
Define your positioning before you source anything. Who is your customer? What do they care about? "Premium sustainable activewear for women over 40" is a brand. "Cheap gym clothes" is a race to the bottom. Your positioning drives every product decision — fabric choices, colourways, sizing philosophy, branding, price point, and marketing channels.
Invest in packaging and presentation. The unboxing experience matters enormously in activewear, particularly for DTC and Amazon brands. Custom polybag sleeves, tissue paper, branded hangtags — all achievable through Chinese packaging suppliers, all make a disproportionate difference to perceived premium. For guidance on how much to invest in customisation at each stage, read our post on white label vs private label.
Protect your supply chain as you grow. If you've built something genuinely proprietary — custom fabrics, unique patterns, exclusive colour ranges — consider confidentiality carefully. Our Secret Label Package ensures your factory relationships, product specifications, and supply chain details remain entirely confidential. It's a popular choice for activewear brands that have invested significantly in product development.

It absolutely can be — and at the right factories, it often is exceptional. China's activewear manufacturing industry is highly sophisticated, with many factories producing for major international brands you'd recognise. The key is choosing the right factory and specifying your quality requirements clearly: fabric composition, weight (gsm), stretch recovery, and colour fastness. A sourcing agent who knows the activewear landscape significantly increases your chances of landing a quality supplier first time.
Most knitted and woven clothing attracts a 12% import duty rate in the UK under the Global Tariff schedule. This is based on the customs value, which includes the product cost, international freight, and insurance. Import VAT at 20% applies on top. Always check the specific commodity code for your product on the UK Trade Tariff website, as rates can vary by fabric composition and product type.
The core steps are: define your brand positioning and target customer; select 2–5 core products to launch with; find a verified manufacturer (ideally through a sourcing agent); order samples and test quality rigorously; refine specifications; place a production order; handle import compliance and customs clearance; and launch. Our Private Label Package guides you through this entire process with Epic managing the factory relationship on your behalf.
For leggings and performance wear, look for nylon-spandex (typically 80/20 or 78/22 blend) or polyester-spandex blends with a minimum 200–240 GSM fabric weight. Four-way stretch with excellent recovery is essential for gymwear. Ask suppliers specifically about squat-proof performance and request a stretch test on samples before ordering. Seamless construction (using circular knitting technology) offers excellent quality at competitive price points for basics like leggings and bras.
Standard samples typically take 7–14 days from confirmation of specifications, plus 3–5 days for air courier delivery to the UK. Budget 2–4 weeks in total from initial enquiry to having samples in hand. For development samples involving new designs or custom fabric specifications, allow 3–6 weeks. Always factor sample lead time into your product launch timeline — rushing this stage reliably leads to production problems.
Yes — and thousands of small UK businesses do, successfully. The key is understanding your full landed cost (including 12% import duty), setting a retail price that delivers the margin you need, and starting with white label or lightly customised private label products to minimise upfront investment. As volume grows, you can increase customisation and negotiate better factory prices. Our White Label Package is specifically designed for UK businesses at this early stage.
Building a branded activewear range around China-sourced products is one of the clearest paths to a profitable UK eCommerce business — provided you get the sourcing right from the outset. Quality, compliance, landed cost management, and supplier relationships all matter enormously in this category.
