What a Shorts Manufacturer Does That a Print Shop Doesn't
The distinction matters more than it sounds. A print shop takes a blank shorts style already made by someone else, adds your logo, and ships. A shorts manufacturer builds the garment: fabric selection, liner or no liner, waistband construction, pocket placement, and seam finishing — developed from your spec or a reference garment, not picked off a shelf.
If you only need a small run of an existing blank decorated with your logo, a local print shop will be faster and cheaper than an overseas factory — that’s not us, and we’ll tell you so upfront. This page is for brands ordering real production volume with their own construction spec: team kits, athletic lines, private label ranges that need to look and fit the same whether it’s piece 1 or piece 500. For the full construction breakdown — inseam options, liner fixes, waistband types — see our private label activewear manufacturer page.
The practical difference shows up in accountability. When the factory that cuts the fabric is the same company you’re talking to, a fit problem or a fabric substitution has one owner — us. Every set is checked against the sample you approved, and if bulk drifts from it, we remake — not just refund.
Shorts Manufacturing Capabilities
Everything below runs in-house — cutting, sewing, decoration, labeling, and packing in one facility. That is not a marketing line; it is why we can hold a 100-piece MOQ and still fix the construction detail most shorts suppliers get wrong.
Training & Athletic Shorts, With or Without Liner
5″ and 7″ inseam training shorts in mesh, polyester interlock, and cotton-poly blends, with or without a mesh brief liner. The liner is the most common construction failure we see in reference samples: cheap mesh liners bunch, the waistband integration is often poorly sewn, and the liner is cut too short to prevent ride-up. We use separate liner elastic and a double-needle attachment at the waistband join, rather than sewing the liner and shell into one seam.
Biker Shorts & Board-Style Shorts
High-rise biker shorts with flatlock construction matching legging specs, and board-style training shorts with a woven shell. Biker shorts run on the same performance fabric and tension calibration as our leggings — see our leggings manufacturer page for the fabric weight (GSM) that determines opacity, which applies to biker shorts the same way it does to full-length leggings.
Private Label, Packaging & Compliance
Custom woven labels, heat-transfer or embroidered logos, hangtags, and care labels from 200 pieces per colourway (screen-printed labels work at lower runs). Packaging runs from printed polybags with header cards to branded boxes. Fabric and trims can be sourced to OEKO-TEX® Standard 100 and GRS specifications on request. You own the design and pattern — see our private label activewear page for how we handle IP and branding ownership.
How to Choose a Shorts Manufacturer
Whether you work with us or not, these are the checks that separate a real manufacturer from a print shop or trading company with a website. They take one email to run.
1. Ask who owns the production line. “Is production in your own facility, or subcontracted?” A factory answers with a location and can put you on a video call from the floor. A trading company or print shop changes the subject.
2. Ask if they manufacture or decorate. If a supplier can’t tell you what fabric the shell is made of, where the liner comes from, or how the waistband is finished, they’re printing on someone else’s blank — fine for a quick small run, not for a private-label programme with real spec requirements.
3. Ask specifically about the liner. Cheap mesh liners bunch and ride up. Ask how the liner elastic is attached to the waistband — a factory that has actually made athletic shorts before will have a specific answer, not a shrug.
4. Check what the MOQ actually means. “MOQ 100” can mean 100 total, or 100 per colour, or 100 per colour per size. Get it in writing. Ours: 100 finished pieces per colour per design, sizes split freely within it.
5. Ask what happens if bulk doesn’t match the sample. This is the question most suppliers dodge. Ours: the approved sample is sealed as the production reference, and if bulk drifts from it, we remake — not just refund.
OEM Development Process: From Spec to Production
You don’t need a complete tech pack to start — a reference garment and a target price get most programs moving. Here is the path either way.
1. Spec & Quotation
Send a tech pack, or a reference garment plus target market, construction (liner/no liner, pockets), and quantity. We quote within one business day and flag anything outside standard range in the first reply, not after sampling.
2. Pattern & Proto Sample
Our pattern room drafts or adapts your block, then sews one proto sample per style in-house at a flat fee, credited against bulk orders. Turnaround 10–14 days. You evaluate fit, fabric hand, and construction before any bulk commitment.
3. Fabric & Construction Confirmation
Once the sample is approved, the fabric, liner, and trims are confirmed against your signed-off standard before bulk cutting begins. That confirmed sample becomes the reference every inspector checks against — not a verbal description of it.
4. Bulk Production & QC
12–18 days depending on construction and volume, with QC at three points: post-cutting measurement checks, mid-production seam and liner checks, and final inspection against the approved sample to AQL 2.5.
5. Shipping & Documentation
FOB Shanghai or Ningbo, China, or CIF/DDP to major ports — duties and freight already included in a DDP quote, so you can compare true landed cost, not just the factory-gate price. Full export documentation included: commercial invoice, packing list, certificate of origin.
Our Terms, In Writing
Most factories make you email three times to learn their MOQ. Here is everything, up front.
| Term | What we commit to |
|---|---|
| MOQ | 100 pieces per colour / design on fabric dyed or sourced to your colour. Sizes are mixed freely within those 100: no size multiplier. (Custom woven labels need 200 pcs per colourway; screen-printed labels work at lower runs.) |
| Pricing | Quoted per style once we see your spec — liner, mesh weight, pocket construction and decoration all move the unit cost, so we don’t publish a flat rate that would be wrong for most builds. Biker shorts on performance fabric are priced the same way as our leggings ($4.80–7.00 FOB at 100 pcs/colour); woven and mesh training shorts quoted separately. |
| Sampling | Sample fee is 100% credited to your bulk order. Not 80% back. Not “free if you order 200+”. The full fee comes off your invoice when you place the order. |
| Sample vs bulk | Your approved sample is the production reference. If bulk drifts from the sample you signed off, we remake it — the “perfect sample, thinner bulk” story does not happen here. |
| Bulk production | 12–18 days after sample approval, including fabric sourcing. |
| Production updates | Photo updates at three stages — cutting, sewing, final QC — sent without you having to ask. Want a live video check mid-run instead? Just message us. |
| Reorders | 10–15 days. This is where working with the actual factory pays off. |
| Payment | 30% deposit, 70% before shipment. |
| Shipping | FOB Shanghai or Ningbo, or DDP door-to-door. We quote both, so you can compare true landed cost — not just the factory-gate price. |
| Certifications | OEKO-TEX® Standard 100 and GRS 4.0. Certificates and our business licence sent on request, shipped with your order. |
| Design confidentiality | Your pattern and spec sheet are developed for your order only. We'll sign an NDA before development starts if you want one in place — just ask when you submit your inquiry. |

Custom Shorts Manufacturer FAQ
We manufacture. Cutting, sewing, liner and waistband construction, decoration, and labeling all happen in our own facility from fabric up.
If you only need a small run of an existing blank style decorated with your logo, a local print shop will usually be faster and cheaper than an overseas factory — that is a different business than ours, and we would rather tell you upfront than take an order that is not a good fit.
The liner is the most common construction failure on training shorts: cheap mesh liners bunch, the waistband integration is often poorly sewn, and the liner is cut too short, which causes ride-up.
We use separate liner elastic and a double-needle attachment at the waistband join instead of sewing the liner and shell into a single seam.
Your approved sample is sealed as the production reference and checked against at three QC points, to AQL 2.5.
If bulk drifts from the sample you signed off, we remake it — we do not quietly substitute a cheaper fabric or construction in production.
100 finished pieces per colour per design, with sizes split freely within that quantity. We do not multiply the minimum by size.
Custom woven labels need 200 pieces per colourway because of label loom setup costs; screen-printed labels work at lower runs.
30% deposit to start production, 70% before shipment. That is the only split you will be asked to pay — no additional fees added later in the process.
Ask, and we’ll show you. We do video calls from the production floor on request so you can see the cutting tables and sewing lines live, not a stock photo.
Our business registration is public and verifiable through China’s official company registry. We can send recent factory video and photos, and our BSCI audit report plus OEKO-TEX and GRS certificates are available on request before you pay anything.
You’ll receive photo updates at three production stages — cutting, sewing, and QC — without having to chase us for them.
A live video walkthrough of your order in progress is available any time you request one, not only before you pay.
Your pattern and spec sheet are developed specifically for your order. If you want a signed NDA in place before we receive your tech pack, we’ll sign one before development starts — just say so when you submit your inquiry.
