How to Source Custom Activewear in China: A Buyer Checklist

A practical buyer checklist for sourcing custom leggings, sports bras, shorts, tops, and similar activewear in China, covering fabric, weight, stretch, fit, sizing, construction, branding, samples, packaging, and supplier confirmation.

Activewear sourcing is difficult to compare from photos alone because garments that look similar can feel and perform very differently depending on fabric construction, weight, stretch, recovery, fit, seams, finishing, and pattern development. The most useful starting point is not a long list of generic fabric percentages. Start with a reference garment or clear photos, explain the intended use and target feel, and identify the construction points that matter. Final fabric composition, weight, fit, color, finishing, labels, quantity requirements, and production feasibility should be confirmed with the selected supplier. 1. Start with the garment type and intended use Share a product photo, existing sample, tech pack, supplier link, sketch, or measurements from a garment that fits well. Explain whether the target is leggings, yoga pants, sports bras, bike shorts, running shorts, tops, jackets, or another activewear style. A low-impact yoga garment, running top, compression-oriented legging, and casual athleisure piece may need different priorities for stretch, coverage, support, breathability, seams, and fit. 2. Treat fabric composition as only one part of the specification A composition label such as polyester/spandex or nylon/spandex does not tell the whole story. Fabrics with similar percentages can differ in knit construction, weight, stretch direction, recovery, density, texture, hand feel, opacity, brushing, and other finishes. Fiber composition target Fabric type or knit construction if known Fabric weight or approximate GSM target Two-way or four-way stretch where relevant Stretch and recovery feel Surface finish, brushing, rib, mesh, or texture Desired softness, compression, support, or drape Opacity or coverage requirement Performance target if genuinely required Material composition, fabric type, weight, stretch, finish, and color shown on a reference product should be treated as a reference configuration rather than a permanently fixed formula. They can be redeveloped around the buyer’s target, subject to garment structure, quantity, intended use, and supplier confirmation. 3. Confirm fit and measurements, not only the labeled size Labels such as S, M, L, or “US size” are not enough to guarantee fit. Different brands use different blocks, grading, ease, rise, inseam, bust, underband, and length standards. Waist, hip, thigh, and leg opening Rise and inseam Total garment length Bust, underbust, body length, and strap length Sleeve and shoulder measurements Waistband or support-panel height Relaxed and stretched measurements where relevant A well-fitting reference sample can be more useful than a generic size chart. 4. Review construction details that affect comfort and performance Seam placement and seam type Gusset shape and placement Waistband height and internal construction Elastic type and placement Lining or support layers Cups or removable pads Straps and adjusters Pockets Mesh panels or ventilation zones Hem construction, zippers, drawcords, or other functional parts If a construction feature affects support, movement, or comfort, show it clearly in photos or mark it on a sample or drawing. 5. Define the target feel instead of relying on vague performance language Terms such as “premium,” “buttery soft,” “compression,” “squat proof,” “breathable,” or “quick dry” can mean different things to different suppliers. Describe what you are comparing: lighter or heavier fabric, softer or firmer compression, more or less stretch, matte or shiny surface, brushed or smooth hand feel, or a particular level of support. If a performance claim will appear in marketing, make sure the actual product and relevant evidence support that claim. 6. Handle color approval with the actual fabric and finish Color can change depending on fiber, dye process, fabric texture, surface finish, lighting, and screen display. If a brand color matters, provide a clear target and agree how it will be approved. A lab dip, fabric swatch, printed strike-off, physical sample, or other agreed reference may be appropriate. For coordinated sets, check that tops, bottoms, mesh, elastic, zippers, labels, and trims look acceptable together. 7. Confirm logo, print, labels, and branding as a system Activewear branding can include heat transfers, silicone transfers, screen printing, embroidery, woven labels, printed labels, size marks, care labels, hangtags, or branded packaging. The appropriate method depends on the fabric, stretch, artwork, position, and desired finish. Artwork and logo dimensions Placement and color Decoration method Stretch area or non-stretch area Main label, size label, care label, and origin information where required Hangtags or retail branding 8. Treat the sample as a fit-and-fabric approval step For activewear, a sample is especially valuable because photos do not show fit, recovery, support, hand feel, or movement well. Fabric feel and thickness Stretch and recovery Opacity or coverage Measurements and fit Waistband or support structure Seam comfort and placement Pads, straps, pockets, and other functional details Logo appearance, color, labels, and packaging If there are several sizes, one approved sample does not automatically prove that grading is correct across the full range. 9. Packaging and assortment should be planned before bulk production Individual polybag or alternative packaging Fold method Size sticker or barcode Hangtag Set packing Color and size assortment by carton Carton marks and retail packaging requirements 10. What information helps produce a more useful quotation? Reference garment, photo, tech pack, sketch, product link, or product code Garment type and intended use Approximate quantity by style Number of colors and target size range Key measurements or a fit reference Fabric target, GSM, stretch, feel, or performance requirement if known Construction details that must be retained Logo, label, and packaging requirements Destination country or market Target price range if you already have one Sample or timing requirement 11. Confirm the final bulk standard before production Before bulk production, make sure the supplier and buyer are referring to the same approved version: sample, measurement chart, fabric, color, logo file, labels, packaging method, size assortment, and any agreed inspection points. Record later changes clearly so an older sample is not accidentally treated as the final standard. What to send Benson Sourcing Start with a garment photo, product link, tech pack, or physical reference plus the approximate quantity. Add the target fabric feel or composition, GSM, size range, measurements, logo, colors, labels, packaging, destination market, and timing if you already know them. Missing points can be clarified during supplier communication and sampling.
