How to choose a custom sportswear manufacturer: seven checks

Send the same brief to each shortlisted supplier. Otherwise, one may quote a lightweight jersey while another includes heavier fabric, shorts and individual packaging. Both prices could be accurate, but they answer different requests.

1. Start with the garment you actually need

A supplier’s general sportswear catalogue is a starting point. Ask to see work close to your order: basketball uniforms if you need basketball kit, for example. Look at neckline construction, panel layout, seams and decoration, rather than judging only the front-facing design.

Also ask which work is done by the supplier and which is outsourced. A production partner using specialist subcontractors is not automatically a poor choice. The useful question is who controls the specification, checks the finished garments and takes responsibility when something is wrong.

2. Turn “good fabric” into a specification

Ask for fibre composition, fabric construction and weight in GSM, meaning grams per square metre. Then check the actual material against your use: movement, opacity, comfort and the fit your players need. GSM describes weight; it does not, by itself, prove quality or performance.

For sizing, request finished-garment measurements and an explanation of how to measure them. A size labelled “medium” is not enough to compare suppliers. Agree measurement tolerances, meaning how much a finished measurement may vary, before you approve production.

3. Clarify the minimum order quantity

Ask whether the MOQ applies to the whole order, each design or each colour. Confirm whether youth and adult sizes can be combined and whether goalkeeper kits or alternate jerseys count as separate styles. Get the answer on the quotation.

For a team, also discuss later additions. Can you reorder two replacement jerseys, or must you meet a new minimum? The first order and a small reorder may have different prices and lead times.

4. Make customization specific

Supply usable logo files, a numbered player list and your colour references. Ask the supplier to confirm the decoration method for each element. A printed crest, embroidery and a sewn patch are different specifications, even when they look similar in a small mockup.

For help matching a finish to the garment, compare sublimation, screen printing and embroidery for teamwear before approving the decoration specification.

Before approving artwork, check spelling, number placement, sponsor proportions and any league requirements you need to meet. Keep one approved file version so an earlier player list does not find its way into production.

5. Approve a sample against a checklist

Ask whether the proposed sample uses your intended fabric, construction, decoration and labels. A stock sample can help you understand workmanship, but it does not confirm every detail of your custom order.

• Fit: compare the garment with the agreed measurements and try it on someone representative of the intended wearer.
• Construction: inspect seams, hems, neckline and inside finishing. Look for loose threads and uneven joins.
• Design: compare colours and artwork positions with the approved specification.
• Wear and care: assess comfort and movement; follow the proposed care instructions for a wash check and note any changes.
• Production match: record the sample version and any remaining changes in writing.

Agree how bulk goods will be checked, who receives the inspection results and how a discrepancy will be handled. A sample approval is not the same thing as inspecting the completed order. Ask what evidence you will receive before dispatch.

6. Compare the full quote, not just the price per jersey

Ask each supplier to separate garments, customization, sample or setup charges, labels, packaging and shipping. List excluded costs too. Use the same quantities, specifications, currency and delivery destination for each comparison.

For international orders, identify the delivery terms and exact destination or handover point. ICC’s Incoterms® rules explain the allocation of delivery tasks, costs and risks between buyers and sellers. Ask your freight provider which rule fits the shipment; an unexplained three-letter abbreviation is not a complete delivery agreement.

Work backwards from the date you need to use the uniforms. Ask for sample preparation, revision, bulk production and transit milestones separately. Confirm which approvals or payments start each stage. A dispatch date is not an arrival date, and extra sample revisions can change the schedule.

7. Check the evidence behind the promises

Confirm the business name on the quotation and invoice, who your contact represents and who receives payment. If account details change, verify the change through a contact method you already trust. Keep the approved specification, payment schedule and process for reporting defects together.

When a supplier mentions certification, ask for the certificate number and the products or materials it covers. OEKO-TEX® STANDARD 100, for example, concerns textiles tested for harmful substances. Use the official Label Check to check a supplied number. Treat that evidence separately from your checks on fit, workmanship and delivery.

If you will sell the garments, check destination-market labelling requirements before approving labels. For US sales, the FTC’s textile labelling guide explains requirements including fibre content, country of origin and identification of the responsible business for most covered textile products. Confirm the requirements that apply to your specific goods; a private-label logo alone is not a complete label plan.

Send a brief that suppliers can actually quote

Copy this starting point and fill in what you know. Mark undecided details as questions instead of letting each supplier make a different assumption.

Sport and garment: [e.g. basketball jersey and shorts]
Quantity: [number of garments or complete kits]
Sizes: [youth/adult and estimated size breakdown]
Design: [colours, logos, names and numbers]
Fabric and fit: [requirements, or request options]
Branding: [neck label, care label and packaging needs]
Sample: [what needs approval and by when]
Delivery: [country, postcode and required arrival date]
Quote: [currency, itemized charges and exclusions]
Please confirm: MOQ rules, sample/revision costs,
production milestones, shipping terms and reorder options.

If you are comparing several suppliers, keep their answers in the same table. Missing information should remain visible as “not confirmed,” rather than being treated as included in the price.
