Custom Tracksuit Manufacturer: Size-Matched Two-Piece Sets
A custom tracksuit is a two-piece set of jacket and trousers in a knit such as interlock, ponte or French terry, using about 0.80–1.20 kg of fabric per set. We build them with non-roll waistbands, reinforced crotch seams and set packing that keeps every top with its matching bottom.

Key takeaways
- Tracksuits use about 0.80–1.20 kg of fabric per set.
- 3.5–5 cm dense woven elastic stops the waistband rolling.
- The crotch seam is 5-thread overlocked or reinforced to prevent splitting.
- Athleisure sets often add contrast side stripes or piping.
- Top and bottom are packed size-matched in one bag, never mixed.
Tracksuits are sold as a set, so they succeed or fail as a set. A good jacket with trousers that split at the crotch, or a carton of mismatched sizes, ruins the programme. Here is how we make custom tracksuits within our casual sets range.
What makes a good tracksuit
Start with a knit that holds its shape. Interlock and ponte resist bagging and pilling, and French terry adds warmth; see our knit fabric guide. The waistband should stay flat, which means dense woven elastic 3.5–5 cm wide, sewn on a multi-needle machine. The crotch seam must not split, since that is the most common failure in knit trousers, and we handle it with 5-thread overlock or reinforcement. Zips are chosen by style: jacket front, invisible pocket and leg opening. Finally, every jacket is packed with its matching trousers.
Construction details
From our casual set bill of materials, the body is interlock, ponte (Roma), “health” fabric or French terry, ≈ 0.80–1.20 kg per set. Cuffs, leg openings and neck take matching or contrast spandex rib, with optional side stripes or piping. The waistband is 3.5–5 cm dense woven elastic, multi-needle sewn. Drawcords are cotton or polyester flat cord with metal eyelets or internal openings. Pocket bags use light cotton jersey or poly-cotton mesh, 120–150 GSM, to avoid bulk. The top carries a main and care label, and the bottom has a back-waist main and care label, marked as a set. Overlock and coverstitch seams use high-stretch polyester thread.

Before you sample
Decide the zip configuration, whether stripes or piping run down the sleeve and leg, and how the waist is adjusted. Note any split-sizing needs at quotation so the size ratio and packing are planned from the start.
Final thoughts
A good tracksuit is two well-made garments that arrive together. Specify the fabric, waistband and zip configuration, approve a set sample, and agree packing at quotation. We confirm MOQ, pricing and lead time with your quote.
FAQ
Frequently asked questions
Which fabric is best for a tracksuit?
Interlock and ponte hold their shape and resist pilling well; French terry is warmer and softer. We recommend options based on your climate, use and brief.
How do you stop tracksuit waistbands rolling?
We use dense woven elastic 3.5–5 cm wide and sew it with a multi-needle elastic machine, which locks the elastic in place.
Can the jacket and trousers be different sizes?
Sets are packed size-matched by default. If your programme needs split sizing, tell us at quotation and we plan the size ratio and packing accordingly.
Can you add side stripes or piping?
Yes. Contrast rib, side stripes and piping are standard customisation options on athleisure sets.
