Production Policy

Direct Factory Manufacturer, Not a Trader

Overfit Seamless knits all collections to order in our Beylikdüzü, Istanbul plant on 20 Santoni Top2V machines. We do not stock or resell finished apparel. Our minimum production volume is 1,000 units per garment style, which can be split across up to 2 distinct sizes and 3 custom colourways. We support brands from initial yarn selection and rapid CAD sampling to export-grade bulk packaging.

Factory Audits
01 / TECHNICAL EXPERTISE

Direct Circular Knitting

Your technical packs and measurement sheets are evaluated directly by programmers operating 28-gauge Santoni circular knitting machinery, avoiding intermediary mistakes.

02 / RAPID SAMPLING

5 to 7 Day Lead Time

Because yarn testing, pattern programming, and machine setup happen under one roof in Istanbul, fit prototypes and counter-samples ship within days.

03 / TRACEABLE QUALITY

Strict Textile Standards

Every lot passes rigorous multi-stage inspections for dimensional stability, non-sheer squat testing, and colorfastness under European chemical certification norms.
