Engineered flat-knit sweaters and knitwear on Shima Seiki and Stoll for US brands: body-mapped structures, technical yarn blends and seamless WHOLEGARMENT construction — produced to your spec, under your label, sourced outside China.
Performance knitwear is engineered, not just knitted. On computerised Shima Seiki and Stoll machines we build structure into the garment — rib zones, ventilation, seamless construction — using technical and natural-blend yarns. Your design and spec, our machines, your label.
Knit-to-shape, no side seams — fewer pressure points and chafe, a cleaner fit for active and base layers.
Body-mapped rib, mesh and tension zones knitted in — support and breathability placed exactly where the design needs them.
Merino and performance blends for thermoregulation, stretch and recovery — supplier-sourced with full certification.
Computerised Stoll CMS & Shima Seiki, 3–14gg — repeatable, consistent engineering batch after batch.
We are a flat-knit specialist — engineered sweaters, base layers, technical mid-layers and knit-to-shape pieces. For cut-and-sew jersey activewear we work through our vetted partner network. We will always tell you straight what is in-house and what is partner-made.
The US activewear and athleisure market runs on technical knit — engineered base layers, merino mid-layers and performance sweaters. The sourcing math is the same as the rest of US apparel: Section 301 and UFLPA have made a China-only supply chain a risk, and the schedule is won at the machine, not on the water — bulk in 2–3 weeks from an approved sample (3–4 weeks at 500–2,000 pcs, 4–6 weeks above that), then 3–5 weeks by ocean to the East Coast, is what keeps a performance line's tight seasonal drops on track. We knit your technical pieces on non-Xinjiang, certified yarns, with FTC labeling and US compliance built in at the factory.
