Build your short in five decisions.
Shorts buyers do not only browse products. They need to decide what short they are building, how long it is, whether it needs a liner, how the waistband holds, and which fabric supports the activity.
Biker, running, gym or compression
Each route has a different fit promise and buyer expectation.
3", 5", 7" or 9"
Length sets the styling direction before pattern work starts.
Brief, mesh, compression or none
The liner choice changes comfort, cost and use case.
High-rise, elastic or drawcord
We align waistband construction with movement and retail fit.
Stretch knit, woven or seamless
Fabric route decides support, drape, breathability and MOQ.
Same category, different manufacturing logic.

A shorts build sheet buyers can scan.
Short type, fabric, liner and MOQ are separated so buyers can brief a style without writing a long spec from scratch.
| Short type | Typical fabric | Liner | MOQ |
|---|---|---|---|
| Long / compression shorts | Nylon-spandex, rib, brushed or seamless knit | Usually unlined | From 100 sets |
| Running shorts | Lightweight woven or quick-dry knit | Brief, mesh or compression liner | From 100 sets |

Coverage, liner and movement proof.
Shorts evidence is organized by buyer decision, not by generic factory process.
Squat-proof opacity check
Opacity is checked on compression fabrics before bulk, especially for dark-to-light colorways and extended sizes.
Liner and inseam selection
Buyer sends inseam length, liner type, fabric goal and target quantity; we confirm the most practical build route.
Private-label branding
Check logo placement against the short’s construction
On biker and gym shorts, check the outer thigh or waistband for heat transfer or silicone 3D. On running shorts with a liner, mark the outer layer on your drawing. Embroidery is for non-stretch panels. We place woven labels at the waist and pack the labelled pieces in-house before export. Send the logo, its intended width and a sketch showing the liner and pockets.
Colour
Keep shell and liner colours separate in the brief
Choose a seasonal shade or give a Pantone reference for the shell. If a style is lined, include the liner colour in your brief. Stock with your logo starts at 100 sets with mixed colours and sizes. Full custom orders are 300–500 pieces per style and colour.
