MOQ from 10 Pieces | Sampling in 7-10 Business Days | Worldwide Delivery

Sports bras that keep the fit you approved, in sampling and in bulk.

Sports bra returns usually trace back to support problems: underbands roll, cups shift, straps dig, or the bulk size block changes from the approved fit. We build low-impact, medium-impact, and high-impact sports bras to your tech pack in Nylon-Spandex or Polyester-Spandex, 180–320 GSM, with support, cups, straps, seams, and measurements checked through sampling before bulk.

Minimum 10 pieces per design and colorway. Sampling 7–10 business days. Bulk 3–5 weeks after approval, depending on volume and construction. Pricing scales with quantity. Private label for startups, gyms, and retail buyers in the USA, UK, Australia, and Europe.

Sports bra fabrics

Sports bra fabrics

The fabric specification depends on the support level and intended activity. A low-impact studio bra, medium-impact training bra, and high-impact running bra should not all use the same fabric behavior or construction.
We work with Nylon-Spandex and Polyester-Spandex from 180–320 GSM. Options include brushed performance knits, ribbed constructions, recycled polyester, and seamless yarn, selected according to support, stretch, recovery, and hand feel.

Key points

  • 180–320 GSM fabric range for low-, medium-, and high-impact bras
  • Nylon-Spandex and Polyester-Spandex constructions
  • Brushed performance knits and ribbed constructions available
  • Recycled polyester and seamless yarn available when specified
  • Fabric selected according to impact level and support target
  • Material specifications can be matched to your tech pack

Stretch, moisture, and comfort

Stretch, moisture, and comfort

Sports bras sit close to the skin and need to support movement without rubbing, trapping heat, or losing recovery after washing. Comfort depends on both the fabric and the support construction.
We can build with four-way stretch, moisture-wicking, quick-dry, breathable knits, anti-odor finishes, and UV-protection finishes. These features are selected according to training, yoga, running, gym, or lifestyle use.

Key points

  • Four-way stretch for movement and support
  • Moisture-wicking and quick-dry options available
  • Breathable knits for training and studio use
  • Anti-odor and UV-protection finishes available when specified
  • Stretch and recovery reviewed during sampling

Stitching and construction

Stitching and construction

Sports bra seams need to hold under tension without irritating the skin. Edges, underbands, cups, and straps must survive repeated wear and wash cycles.
Construction can include flatlock seams, overlock, cover stitching, bonded seams, reinforced underbands, power mesh panels, and adjustable straps. Measurements, cup placement, underband, straps, and stitching are checked during QC.

Key points

  • Flatlock seams can help reduce skin irritation
  • Overlock, cover stitching, and bonded seams available
  • Reinforced underbands for support
  • Power mesh panels and adjustable straps can be added
  • Cup placement and measurements checked before packing

Support and fit engineering

Support and fit engineering

Support level must be built into the pattern, not guessed after the sample. Underband height, strap width, cup shape, padding, and compression all affect how the bra performs.
We develop low-impact, medium-impact, and high-impact sports bras with removable cups, molded padding, reinforced underbands, power mesh panels, and adjustable straps where required.

Key points

  • Low-, medium-, and high-impact support levels available
  • Removable cups and molded padding can be specified
  • Underband and strap construction reviewed during sampling
  • Fit can be matched to your size chart or tech pack
  • Approved measurements become the production reference

Customization options

Choose from our full range of decoration techniques to create your signature look.

Printing methods

Screen print, sublimation, silicone transfer, reflective graphics, puff print, high-density logos, chest marks, back marks, and underband artwork can be developed for low-impact, medium-impact, and high-impact bras. Pantone matching is available so the color you approve is the color that ships.

Embroidery and branding

Embroidered logos, tonal embroidery, 3D embroidery, woven emblems, decorative stitch, and small branding details can be used where the fabric, strap, or panel construction can hold the stitch without pulling or irritating the wearer.

Private label components

Woven labels, heat-transfer neck labels, care labels, size labels, branded straps, branded underbands, removable-cup notes, hangtags, barcode stickers, and retail packaging can be set to your brand guidelines before bulk starts.

Fabric and color development

Custom fiber mix, rib texture, compression level, dye color, power mesh placement, cup color, elastic color, and performance finish can be developed around your support level. The bra is yours, not a relabeled stock style.

Branding, logistics & shipping

Every order is managed from label printing to your doorstep.

Private label production

Every order can ship with your woven labels, heat-transfer branding, branded elastics, hangtags, barcodes, size labels, and retail-ready packaging. Spec this at sampling so bulk isn’t waiting on trims.

Quality control and inspection

Each piece is checked before it reaches you (fabric, in-line sewing, measurement, print, then an AQL review before packing) so the underband, cup, and size you approved in sampling are what you get in bulk.

Global logistics

Packed to retailer spec and shipped through courier and freight partners. Export documentation included for USA, UK, Australia, and Europe programs.
