Engineered with 28-gauge Santoni circular knitting technology and high-tenacity multi-filament yarns to eliminate chafing, improve compression resilience, and streamline wholesale operations.
Founded in 2019 in Beylikdüzü, İstanbul, Overfit Seamless operates as an authentic prime manufacturer, eliminating intermediary brokerage and delivering complete control over yarn selection, gauge calibration, and dye house chemistry.
We do not outsource knitting. Our plant runs 20 Santoni Top2V gauge-28 machines around the clock, producing cylindrical seamless tubes with integrated mesh and localized compression.
Because programmers work side-by-side with circular machine operators, physical counter-samples and pattern grading take days instead of months, speeding your time-to-market.
Located in İstanbul, our shipments reach Frankfurt, Paris, and London within 3–5 transit days by road or air cargo, avoiding six-week maritime choke points and container demurrage costs.
Under the EU-Türkiye Customs Union framework, our activewear qualifications allow frictionless, duty-favorable entry into European ports with streamlined ATR/EUR.1 documentation.
| Evaluation Parameter | Our In-House Santoni Seamless Tech | Traditional Cut & Sew Operations | Sourcing Benefit |
|---|---|---|---|
| Structural Integrity | Knitted in single continuous cylinder tubes | Multiple planar fabrics stitched with flatlock seams | Zero Side Seam Chafing |
| Fabric Scrap Waste | Knitted to net shape; under 3% cutting loss | 18% to 25% waste from marker cutting scraps | Lower Environmental Impact |
| Elastic Stretch Recovery | Multidirectional 360-degree anatomical micro-stretch | Bi-directional stretch constrained by rigid seam threads | Consistent Squat-Proof Fit |
| Minimum Production Unit | 1,000 pcs split across 2 sizes & up to 3 custom colours | High MOQs required for custom textile knitting runs | Better Working Capital Turnover |
B2B fitness apparel procurement is moving toward sustainable raw materials, localized supply chains, and technical yarn innovations. Here is how modern brands are adapting.
Global procurement heads are shifting away from virgin petroleum polyester toward recycled Q-NOVA and ECONYL regenerated nylon. These sustainable materials run cleanly through circular knitting machines while retaining tensile elongation, non-sheerness, and abrasion resistance.
Instead of relying on heavy elastane blends, brands are programming targeted knit zones directly into the circular cylinder. This approach delivers breathability behind the knee and firm core support at the waistband without adding weight or stitching.
Faced with volatile consumer demand and container transit disruptions, activewear brands are reducing lead times by nearshoring production to Turkey. This enables faster inventory replenishment and helps prevent end-of-season markdowns.
Our ISO-certified manufacturing protocol maintains strict four-point inspection standards across every stage of the production cycle.
Selection of certified high-tenacity nylon 6.6 filaments and Creora elastane. Computerized spectrophotometer checks ensure exact Pantone match tolerances (Delta E < 0.8).
Design files and grading tables are coded into digital control programs for our Santoni Top2V machines. Prototype samples are completed in 5–7 days for fit validation.
Continuous-loop circular knitting runs with real-time electronic needle monitors, preventing structural drop-stitches and maintaining consistent 320–360 GSM fabric density.
Garments undergo heat-setting, anti-microbial finishing, silicone transfer labeling, and a 100% manual inspection before export-ready packing and dispatch from İstanbul.
Key information regarding production minimums, yarn chemistry, laboratory certifications, and international logistics.
We are a direct manufacturer based in Beylikdüzü, İstanbul. We own and operate 20 Santoni Top2V circular knitting machines. Our yarn sourcing, pattern drafting, knitting, and packaging are handled directly by our in-house production team.
Our standard MOQ is 1,000 finished pieces per design. To help you balance your inventory, each 1,000-piece order can be split across up to 2 size grades and up to 3 custom colorways (for example, 500 Medium and 500 Large across two colors).
Physical sampling runs take 5–7 business days once your tech pack and yarn specifications are confirmed. Full commercial batch production typically ships within 28–35 business days following final sample sign-off and lab-dip approval.
Yes. Our private label program covers bespoke waistband knitting, jacquard patterns, heat-pressed silicone transfers, customized care labels, recycled hangtags, and barcode-ready polybag packaging.
We use high-gauge 28-cut cylinders combined with double-covered air-jet interlaced filaments, delivering a dense 320–360 GSM interlock weave that prevents sheerness under high-strain extension.
Consignments bound for major European distribution centers arrive in 3–5 transit days by road or air freight. For North American buyers, air cargo to JFK/ORD takes just 48–72 hours, helping you respond quickly to sudden demand spikes.
Send us your tech pack or reference sample. Our technical sales team will provide a comprehensive engineering review, material recommendations, and clear production timelines within 24 hours.
