- Knitwear — India's "T-shirt City," roughly 90% of India's knitted garment exports pass through here.
- Market tier
- Mid, with a growing mid-fashion segment (children's and women's knits for retailers like Marks & Spencer).
- Primary raw material
- Domestic cotton — India is the world's largest cotton producer by volume.
- Distinctive technology
- Deep vertical integration — spinning, knitting, dyeing and garmenting often under one ownership group.
- Typical certifications

- Commercial note
- Over 300,000 people employed directly in the cluster; strong forward-integration from yarn spinners into full garment production.
Bangladesh
Four clusters carry nearly all of the country's export production.
- Gazipur — Vertically integrated knitwear, the single densest cluster (1,900+ factories).
- Dhaka metro / Savar / Ashulia — Large-scale knit and woven production for global fast-fashion retailers.
- Narayanganj — Denim, historically the country's knitwear heartland.
- Chittagong — Woven production and export-processing-zone infrastructure, anchored by port access.
- Market tier
- High-volume, cost-driven — the reference point for basics at scale.
- Distinctive technology
- Bangladesh now hosts the highest number of LEED-certified green garment factories of any country, a genuine shift from its earlier reputation.

Pakistan
- Specialization
- Sialkot — vertically integrated custom production (knit, dye, cut, sew, embroider, pack all under one roof), technical sportswear, leather outerwear; Faisalabad — cotton and denim, with wash technology now closing the gap on Turkey.

- Distinctive niche — Pakistan is one of the only major production countries built around small custom orders (50–500 unit minimums), where China and Bangladesh are optimized for 500–5,000+ unit runs.
- Primary raw material
- Domestic cotton — roughly 5% of world cotton output.
- Distinctive technology
- Full synthetics processing (polyester-spandex blends, moisture-wicking fabric) built in-house, giving sportswear manufacturers control from raw material to finished garment.

- ISO 9001, BSCI, SEDEX common at the certified end of the Sialkot cluster.
- Commercial note
- The go-to district for independent and small brands who can't meet the minimum order quantities of larger Asian mills.
