Sports Bra (Medium Support) — Custom in Portugal

Why Medium Support Sports Bras Are Essential for Activewear Brands

Medium-support sports bras bridge the gap between low-impact bralettes and high-compression performance styles. They deliver stability for low-to-mid intensity activities (yoga, pilates, cycling, studio training) while preserving a natural range of motion. In 2025 the category is a retail sweet spot: shoppers want reliable support, sustainable materials, and a comfortable fit that wears well every day.

Athleisure Basics produces custom medium support sports bras in Portugal, combining technical fabrics, digital fitting tools, and traceable sourcing so brands can launch market-ready collections with confidence.

Custom Manufacturing of Medium Support Sports Bras in Portugal

Portugal is now a leading hub for premium athleisure production thanks to experienced garment technicians, nearby technical mills, and advanced sampling capabilities (3D prototyping, digital grading). Proximity to European markets reduces transit time and simplifies compliance for brands selling in the EU and UK.

Our full-service offering covers fabric sourcing, pattern creation, sampling, cut & sew, finishing, and eco-packaging. Brands can choose private label or OEM paths and benefit from transparent certifications like OEKO-TEX® and GRS when required.

Fabrics That Define Medium Support Performance

The fabric system dictates support, recovery and comfort. Top-performing blends include:

Recycled Nylon + Elastane — smooth hand, high recovery, excellent for performance and studio wear.
Polyester Interlock — moisture management, color retention for outdoor training and frequent washing.
Seamless Knits — body-conforming, reduced seams for comfort and lower waste.
Organic Cotton Blends — lifestyle collections where softness and natural fiber claims matter.

Design Customization & Technical Features

Brands can customize virtually every functional and aesthetic element of a medium support sports bra:

Strap styles: racerback, U-back, cross straps for movement or style
Padding options: removable cups, molded seamless cups, or no padding
Support panels: reinforced gussets, underbust elastic, side-stays for added stabilization
Branding: woven labels, silicone prints, heat transfers, custom packaging
Size range & grading: XS–XXL or extended sizes by request

We use 3D digital grading and real-body fit sessions to validate patterns and reduce size-related returns.

Sustainability & Ethical Production

Sustainability is table-stakes for modern activewear. Key practices we implement:

OEKO-TEX® and GRS-certified fabrics when requested
Solar-powered production facilities and localized sourcing
Closed-loop water and dye systems to cut pollution
Recycled and minimal-waste packaging solutions

These measures support brand transparency and often improve conversion when highlighted on product pages.

Lead Times, MOQs & Cost Transparency

Typical timelines depend on order size and complexity:

Sampling & patterning: ~1 week with digital prototyping
Fabric sourcing: 1–2 weeks depending on certification and availability
Production & assembly: 3–8 weeks depending on MOQ and style

For brands starting small, our low MOQ programs (100–300 units) minimize risk and enable testing. For more on small-batch production, see: Low MOQ Clothing Portugal: A Startup’s Guide.

Quality Assurance & Compliance

Quality checks are performed at multiple stages: incoming fabric inspection, inline QC during assembly, and final full-garment testing. We document inspection reports and can provide compliance paperwork required for EU and North American retailers.

Practical Tips for Brands Working with Portuguese Manufacturers

Prepare a clear tech-pack: accurate measurements, stitch details, and materials speed sampling. Use our guide: Clothing Tech Pack Guide.
Start with a small MOQ: validate fit and colorway through a limited run before scaling production.
Use digital sampling: 3D prototypes reduce physical prototyping costs and time.
Request certifications early: if you want OEKO-TEX® or GRS fabrics, confirm availability at RFQ time.
