Factory Direct Excellence
Knitted as one piece, engineered with zero side seams.
Overfit Seamless operates an advanced circular knitting plant in Beylikdüzü, İstanbul, producing high-performance seamless activewear, yoga wear, and bodywear for prominent private-label brands across North America and Europe. From technical yarn selection to bulk packaging, our integrated ecosystem handles every production stage A-to-Z under one roof.
Seamless activewear is tubular-knit on precision Italian circular machines. By eliminating abrasive side seams, garments achieve an adaptive second-skin fit with balanced 4-way stretch, targeted compression ribbing, and open-mesh ventilation woven directly into the structural substrate.

B2B Sourcing FAQ
Essential procurement clarifications.
Straightforward guidance regarding production minimums, prototyping cycles, material capabilities, and transatlantic shipping operations.
Yes. Overfit Seamless is a direct manufacturing plant in İstanbul, Turkey. We produce full private-label athletic apparel—including woven heat-transfer neck labels, custom hangtags, barcoded polybags, and brand-specific carton markings.
Our baseline production minimum is 1,000 pieces per style. You may divide this batch across up to 2 sizes and up to 3 custom colorways (e.g., 500 Medium, 500 Large distributed among your selected pantone shades).
Sourcing from Turkey offers geographical speed, superior raw materials, and simplified commerce. Transit to Europe takes days by truck or air instead of over a month on ocean container ships. Furthermore, sample iterations take 5-7 days rather than weeks, dramatically accelerating speed-to-market.
We are a direct factory facility. We run 20 Santoni Top2V seamless circular knitting machines in our plant located in Beylikdüzü, İstanbul. We do not intermediate through sub-contractors, which allows us to ensure rigid batch quality control and on-time order departures.
Yes. If you provide a physical sample or reference garment, our technical knitting programmers will deconstruct the gauge, yarn elasticity, and compression bands to build the programming card and create fit-matching counter-samples.
