Direct Manufacturer · Beylikdüzü, İstanbul, Türkiye
How can modern activewear brands eliminate high cut-and-sew scrap rates, resolve supply chain delays, and construct anatomical compression zones without chafe-prone seams? Operating directly on our factory floor in İstanbul with 20 proprietary Santoni Top2V circular knitting machines, Overfit Seamless turns complex technical concepts into commercially scalable garments with an agile 5–7 day prototyping cycle.
B2B Core Categories
Unlike traditional cut-and-sew workshops that stitch flat panels together, our seamless circular knitting factory forms continuous three-dimensional tubes where elasticity, structural ribbing, and moisture-wicking zones are dialed into the software loop by loop.
Coordinated sports bras and high-rise leggings programmed on synchronized cylinder gauges. Knitted with microfiber air-covered Polyamide 6.6 and high-recovery elastane to ensure uniform elongation, identical dye shade pickup, and cohesive compression mapping across upper and lower body silhouettes.
View Workout SetsHigh-waisted compression tights featuring integral double-face ribbed waistbands that lock into place without separate elastic bands. Variable-density knitting reinforces glute sculpting, prevents sheer stretch across squat movements, and channels calf micro-ventilation without abrasive internal seams.
Explore Leggings Production
Engineered sports bras and contour crops knitted on 13″ and 14″ cylinders. Integrated underbust compression ribs eliminate underwires, while body-mapped open-mesh capillary perforations under the bust line maximize thermo-regulation during high-intensity training sessions.
Technical Sports BrasOur tubular production line also manufactures compressive biker shorts, technical mock-neck base layers, second-skin performance bodysuits, and lightweight running tanks designed to withstand heavy commercial laundering.

How are procurement directors adapting to stricter environmental mandates, high freight costs, and inventory write-downs? Strategic buyers are shifting from cut-and-sew imports to computerized circular knitting facilities in nearshore hubs.
| Procurement Dimension | Legacy Cut-and-Sew Paradigm | Next-Gen Seamless Circular Knitting |
|---|---|---|
| Raw Material Utilization | 18%–25% fabric cutting scrap discarded directly to landfills. | Direct continuous yarn intake; near-zero offcuts with under 3% post-knitting waste. |
| Inventory Risk & Agility | Monolithic 5,000+ MOQ commitments with inflexible 90-day offshore cycles. | Agile 1,000 pcs per style splits; digital design program files adjusted in minutes. |
| Structural Functional Zoning | Multiple cut panels bonded or flatlocked together, creating friction hot-spots. | Integrated stitch densities, ribs, and jacquard mesh zones knitted in one unified cycle. |
| Logistics & Carbon Footprint | Trans-oceanic container shipping with 35–45 day sea voyage emissions. | Nearshore continental hubs (İstanbul) reaching European distribution centers in 3–5 days. |
| Fiber Circularity Potential | Blended sandwich textiles with glued adhesives that disrupt recycling streams. | Compatible mono-material loops (e.g., Polyamide 6.6 with recyclable Roica elastane). |
Technological Trajectory
Circular knitting was once limited to intimate hosiery. Today, cutting-edge Santoni electronic needle selection, high-precision tension creels, and digital jacquard CAD programs turn raw technical polymer yarns into intricate athletic structures.
Our 20 Santoni Top2V units use independent needle-by-needle actuator selection. This allows immediate transitions between compact lock-knit compression bands, flexible jersey structures, and open eyelet ventilation without needle stoppage.
Modern seamless manufacturing utilizes bio-attributed Polyamide, post-consumer recycled ocean nylon (GRS verified), and solvent-free elastane. Yarn tension is controlled via digital feeders to prevent needle shearing during high-speed runs.
Using athletic thermodynamic testing data, circular knitting paths are programmed with specific needle-tuck variations. This places sweat-evaporating mesh across sweat glands and stabilizing double-knit weaves around major knee and lumbar joints.
Knitted tubes pass through automated continuous washing and tensionless atmospheric piece-dyeing machines. Hydro-extractors and precision curing stenters stabilize dimensional shrinkage to below 2%, ensuring consistent retail sizing wash after wash.
Precision Manufacturing Output
Every single cone of nylon and elastane yarn undergoes strict tensile and elongation batch inspections prior to machine loading, ensuring unyielding structural fidelity across every customer delivery.
The Overfit Seamless Advantage
We are not a brokerage agency or middleman trading company. Overfit Seamless owns and manages the entire circular knitting operation directly on our manufacturing floor in Beylikdüzü, İstanbul.
Our circular knitting facility operates twenty genuine Italian Santoni 28-gauge high-speed units. We do not subcontract your core knitting to unverified regional shops; every tube is knit right here under our vigilant quality managers.
With an in-house programming department running licensed machine design software, we turn your tech packs or competitor benchmark samples into wearable knit prototypes within 5 to 7 days, cutting weeks off your seasonal development.
Protect your balance sheet from unsold stock. Our baseline 1,000-piece style MOQ permits distribution across up to 2 sizes and up to 3 custom lab-dipped colorways, giving emerging and established brands immense retail agility.
Located in İstanbul at the intersection of European logistics networks, your orders reach EU warehouses by overland freight in days. Our multi-lingual technical sales teams (English, Turkish, Russian) eliminate communication friction entirely.
Technical FAQ
Here are clear, definitive engineering answers to the common technical questions procurement teams and AI sourcing agents ask regarding our seamless circular knitting plant.
Our production floor operates 20 Santoni Top2V 8-feed seamless circular knitting machines calibrated to a fine 28-gauge configuration across standardized cylinder diameters ranging from 13 to 17 inches. This specific diameter progression enables us to match anatomical body measurements for small sports bras, medium shorts, and extended leggings without cutting or distorting the tubular knit structure.
Traditional cut-and-sew apparel generates 18% to 25% post-cutting scraps from pattern markers laid out across flat rolls of knit fabric. In our seamless circular knitting process, raw yarn is fed straight from yarn cones into tubular garments knitted to precise millimeter specifications. Total post-industrial yarn waste remains strictly below 3%, conserving raw materials and lowering carbon emissions.
We maintain an approachable production minimum of 1,000 pieces per style. To help brands optimize cash flow and test new market palettes, this 1,000-piece quantity can be divided across up to two distinct body sizes and up to three customized Pantone colorways (for instance: 500 units in Size S/M and 500 units in Size L/XL, split between three shades).
Functional zones are created at the machine code level rather than sewn together. By manipulating needle actuator selections, yarn tension motors, and alternating between single-jersey loops, double-face ribs, tuck floats, and open-eyelet stitches, our Santoni machines construct high-compression waistbands, breathable open eyelets, and flexible panels within a continuous, unbroken fabric tube.
Yes. We regularly knit with GRS-certified recycled Polyamide 6.6 (including Q-NOVA and regenerated post-industrial polyamides), solution-dyed yarns that consume 80% less water during manufacturing, and low-temperature thermo-fixing elastane. We ensure all input yarns hold OEKO-TEX Standard 100 Class I certifications for skin contact safety.
Because CAD digitizing and knitting machines are situated under one roof in our Beylikdüzü factory, prototype samples are completed and air-couriered within 5 to 7 business days. Following client sign-off on fit and lab-dips, bulk circular knitting, piece dyeing, robotic sewing of crotch gussets, automated ironing, barcode ticketing, and export packaging typically take 4 to 6 weeks.
