Performance apparel engineering
Fenalt delivers end-to-end, fully managed gymwear manufacturing for high-performance activewear brands, fitness labels, and technical athletic wear startups.
Technical gymwear requires precise fiber selection, engineered dimensional elasticity, and reinforced seam construction to withstand dynamic kinetic stress and repeated laundering. Our partners use four-needle six-thread flatlock machinery, high-gauge circular knitting, and heat-transfer bonding systems while Fenalt manages every technical variable from lab dips to final audit.
Direct answer
Fenalt operates as a fully managed apparel manufacturing solution, not an unmanaged broker or directory. We translate tech packs into precise CAD patterns, source performance synthetic and natural blends, match specialized athletic machinery, and coordinate the complete supply chain from raw-material knitting and dyeing to export.
Our standardized operations control technical variables including recovery force, GSM, stitch density, body mapping, and decoration chemistry. Every production run is governed by rigorous inspections using the ANSI/ASQ Z1.4 Level II standard with an AQL 2.5 acceptance threshold.
Silhouette engineering
Each cut is developed around body mapping, localized compression, and the movement pattern of the intended training use.
Compression tanks and rashguards use 15%–25% elastane for muscular containment and reduced drag, with ergonomic raglan sleeves or cross-back panels for scapular rotation. Engineered sports bras combine encapsulated cups, wide elastic chest bands, and reinforced racerback or criss-cross straps for medium to high-impact support.
High-waist leggings and tights use ergonomic paneling, stay-put waistbands, gusseted crotches, and optional laser-cut phone pockets. Diamond or triangle gussets distribute tension and remove the failure point created by a central seam.
Relaxed training shirts use breathable synthetic or triblend knits with dropped armholes, split hems, and extended scoop tails. Dual-layer shorts combine a four-way-stretch woven outer shell with an internal compression liner, bonded zip pockets, and elastic drawcord waists.
Tapered profiles use articulated knee darting, rib-knit calf panels, and deep zip pockets in lightweight interlock or French terry. The pattern keeps the leg mobile while preserving a clean athletic silhouette.
Material selection
GSM, moisture management, recovery force, and opacity all need to be specified together for technical activewear.
| Fabric | Composition | Weight | Performance | Best suited for |
|---|---|---|---|---|
| Nylon-spandex interlock | 75% Nylon / 25% Elastane | 220–300 GSM | Second-skin hand, high compression, four-way stretch, opaque coverage | High-impact leggings, sports bras, fitted shorts |
| Polyester-spandex jersey | 85% Polyester / 15% Elastane | 160–220 GSM | Moisture-wicking, rapid-dry finish, clear sublimation print | Performance T-shirts, compression tops, light layers |
| Polyester-nylon seamless knit | 60% Nylon / 35% Polyester / 5% Elastane | 200–260 GSM | Tubular, friction-free, variable-density breathability zones | Seamless leggings, crop tops, body-mapped shirts |
| Cotton-poly-elastane blend | 56% Cotton / 38% Polyester / 6% Elastane | 240–320 GSM | Soft brushed hand, breathable stretch, durable recovery | Lifestyle joggers, oversized hoodies, pump covers |
| Recycled PET performance blend | 80% Recycled Polyester / 20% Elastane | 200–250 GSM | Crisp moisture management with GRS-certified origin | Eco-focused activewear and print-heavy collections |
Technical construction
Standard seam construction fails under athletic strain. Fenalt specifies machines, thread elongation, and stress-point reinforcement for each performance fabric.
Four-needle, six-thread flatlock creates an abutting zero-overlap join. It removes the inner seam ridge that causes chafing during high-repetition training.
Four-thread overlock construction is used on non-friction seams that need lateral expansion, including outer-leg seams and armhole joins.
Triangular or diamond gussets distribute mechanical strain through the crotch and eliminate the central four-way cross seam.
Continuous-filament textured nylon or high-elongation core-spun polyester threads are selected to match fabric stretch. Pocket entries, side slits, and drawcord exits receive bar-tacks or thermal TPU bonding.
Decoration and presentation
Technical elastane fabrics need flexible decoration, while trims must survive sweat exposure and repeated commercial laundering.
Flexible silicone inks can stretch up to 200% without cracking, making them suitable for raised logos on high-stretch activewear.
Best for synthetic or high-polyester blends; gaseous dye infuses the polymer so breathability and stretch remain intact.
Micro-prismatic films can be placed on calves, back hems, and chests for low-light visibility.
Cotton-rich pump covers and lifestyle fleeces can use soft-hand, zero-hand-feel printing.
Brand system
Jacquard logos, silicone anti-slip grippers, or custom internal drawcords.
Tagless heat-transfer labels, anodized aglets, rust-proof eyelets, and auto-locking nylon coil zippers.
Self-seal or slide-seal polybags with warning labels, SKU barcodes, moisture absorbers, and branded outer mailers or boxes.
Fit approval
Performance garments need physical movement validation before bulk fabric and trims are released.
Tech pack measurements become digital master patterns graded across the requested size range.
A close-match swatch is used to evaluate silhouette, seam placement, and base fit before the exact performance fabric is committed.
Live fit models test stretch limits, waistband rollover, seam comfort, and movement through dynamic athletic exercises.
The golden sample uses bulk fabrics, trims, labels, and decoration. Bulk begins only after formal buyer approval.
Commercial planning
Structured order parameters keep performance collections responsive without forcing unnecessary inventory.
Managed quality assurance
Performance apparel is inspected for function, recovery, appearance, and safety before export.
Fabric is stretched to 150% lateral tension over high-contrast backdrops to verify opacity across lighting conditions.
Samples are held under constant pull tension to measure permanent deformation against elastic recovery.
Accelerated wash tests evaluate bleeding, dye transfer between panels, and elastane degradation.
Finished garments are measured against the tech pack using standard commercial tolerances, and every garment passes metal detection for broken needle fragments.
Operational oversight
One technical partner keeps material decisions, fit approval, bulk execution, quality, and export connected.
Submit sketches or tech packs. Fenalt audits specifications, calculates yarn and trim yields, and issues transparent, all-inclusive pricing.
Synthetic or natural blends are knitted, dyed, and matched through lab-dip strike-offs for Pantone approval.
Master patterns and proto samples are developed for physical fit review and wear testing.
The technical team manages cut-and-sew output, stitch density, machine calibration, and assembly-line quality.
Independent engineers conduct inline and final pre-shipment inspections to ANSI/ASQ Z1.4 Level II.
Packaging, customs documentation, DAP courier delivery, or FOB sea-freight dispatch is coordinated to the agreed destination.
Questions and answers
Fenalt's standard MOQ is 50 pieces per style. This low threshold enables activewear brands to launch structured collections with varied colorways without taking on high inventory risk.
Yes. We build master production patterns directly from your tech packs and measurement specifications. If you do not have a completed tech pack, our engineering team can translate physical garments or design sketches into production-ready CAD patterns.
Silicone heat transfer printing and high-stretch screen-print inks are optimal for elastic fabrics because they flex without cracking or lifting. For multi-color all-over designs on polyester blends, dye sublimation is recommended.
Fenalt uses high-density circular knits with 18%–25% elastane and appropriate GSM, typically 220–300 GSM for bottoms. Every fabric batch undergoes a 150% stretch opacity audit before cutting.
Sampling requires 10–15 days for production plus 3–5 days for courier shipping. Bulk production takes 15–20 days from pre-production sample sign-off to export dispatch; transit varies by courier or sea freight.
Yes. We execute lab-dip strike-offs against Pantone Matching System references through certified dye houses, checking batch-to-batch color consistency and colorfastness against sweat and washing.
