Precision Cutting
Multi-layer cutting with CAD patterns and automated grading for accurate inseams and sizing.

GenXport is a custom gym shorts manufacturer for US activewear brands, gyms, and teams. Get performance-fabric shorts in your inseam, fit, and branding, with low MOQ, in-house QC, and export-ready delivery.

A direct manufacturer for activewear brands and teams that need consistent, branded shorts - not a reseller.
GenXport is a gym shorts manufacturer serving US and international activewear brands, gyms, retailers, and startups. You send the design and tech pack; we deliver finished, labelled shorts ready to sell.
We make custom gym and athletic shorts in-house, from pattern and cutting through sewing and decoration, with quality checks before every shipment. That keeps fit, fabric, and sizing consistent across the whole run.
One accountable team handles sampling, production planning, and QC, so your specs and timelines stay clear from first sample to reorder. We support both new brands and scale-ups with low MOQ production.
Build one style or a full shorts range. We produce gym, training, and athletic shorts across fits and inseams.

Lightweight performance shorts for lifting, HIIT, and everyday training.

Light, quick-drying shorts with split or v-notch hems and inner liner.

Outer short with a bonded compression liner for support and coverage.

Longer-cut mesh shorts with team colours, names, and numbers.

Reinforced, wide-range-of-motion shorts for ring and gym use.

Cotton-poly fleece shorts for warmups, lounge, and athleisure lines.
We also build matching activewear pieces. Explore sibling lines like cargo shorts and men's activewear, plus leggings for a full bottoms range. Need running-specific kits? See our running uniform manufacturing.
Everything runs under one roof, so quality and timelines stay under control.
Multi-layer cutting with CAD patterns and automated grading for accurate inseams and sizing.
Flatlock and overlock seams that reduce chafe and hold up to training.
DTF, sublimation, embroidery, and vinyl handled internally for branding control.
Every garment checked during and after production before release.
We match the fabric to the workout, so the shorts wick sweat, move freely, and last.

Fit is where gym shorts win or lose. We build the inseam, liner, and pockets your line needs.
We confirm every fit detail at sampling, so your bulk run matches the approved fit across all sizes.
GenXport is a low-MOQ manufacturer, so you can launch a shorts line without a large first run. We quote each project on fabric, design, branding, and quantity, so the price is real.
Pricing gets more efficient with volume. A typical first run starts around 50 to 100 pieces per design, and we confirm your exact minimum on quote.
See typical minimums in our MOQ and pricing guide, or request a quote for your shorts.
Plan around clear timelines, backed by capacity to scale through a season.
Sampling usually takes about 1 to 2 weeks, and bulk production about 3 to 5 weeks after you approve the sample, depending on quantity and decoration.
Our factory runs about 2,500 pieces per day, scalable to 15,000, so you can grow from a first drop to full restocks without switching partners. We respond to new inquiries within 24 hours.
We run multi-stage QC during production and a final inspection before shipment release. Every short is checked against your approved sample for fit, inseam, seam strength, and print placement.
