Custom T-Shirt Manufacturer in the USA Starting at 100 Pieces
Sigma Apparel is a leading custom t-shirt manufacturer serving brands, startups, and businesses across the USA and worldwide. With over a decade of experience in t-shirt manufacturing, we deliver high-quality garments with a low minimum order quantity of just 100 pieces per design, giving your brand the flexibility to launch, test, and scale without risk. From cut and sew t-shirts and private label manufacturing to bulk corporate orders, we handle every detail from fabric sourcing to final shipment.
The #1 Cut and Sew T-Shirt Manufacturer with a Low MOQ of 100 Pieces
As a dedicated cut and sew t-shirt manufacturer, Sigma Apparel gives you total control over every detail, fabric weight, construction, silhouette, and fit. Unlike manufacturers that work with pre-made blanks, our cut and sew process starts from raw fabric, meaning your t-shirt is built entirely to your specification. We cater to fashion brands, activewear labels, streetwear lines, and corporate clients across the United States and internationally.
Our t-shirt manufacturing facility produces V-necks, crew necks, polo tees, long-sleeves, oversized fits, and more — in any fabric you choose. We keep our minimum order quantity at just 100 pieces per style and color, which makes us the ideal t-shirt manufacturing company for startups launching a first collection, as well as established brands scaling into new styles. Every order comes with a detailed tech pack and physical sample before bulk production begins.
Private Label T-Shirt Manufacturers for Your Clothing Line
Sigma Apparel is a trusted private label t-shirt manufacturer for brands that want to launch or grow their clothing line under their own name. We manufacture custom t-shirts complete with your woven or printed labels, hangtags, and retail-ready packaging — all while keeping your designs fully confidential under a non-disclosure agreement. Our private label t-shirt manufacturing service is used by DTC brands, gym wear labels, streetwear companies, and promotional merchandise businesses across the USA, UK, Canada, and Australia.
Whether you need a single signature tee or a complete capsule collection, we offer the full package: fabric selection, custom cut and sew, screen printing, embroidery, sublimation, labeling, and packaging under one roof. Our t-shirt manufacturing catalog spans a wide variety of weights, colors, styles, and customization options, from 180 GSM classic cotton tees to 220 GSM premium heavyweight blanks. You choose the fabric, we handle everything else.
Bulk T-Shirt Manufacturing for Corporate, Retail & Brand Growth
Need large-volume custom t-shirts for your business, event, or retail distribution? Sigma Apparel’s bulk t-shirt manufacturing handles orders from 100 pieces to 100,000+ units with consistent quality at every scale. We work with corporate clients needing branded uniforms, sports teams ordering custom tees, non-profits running merchandise campaigns, and retail brands restocking their bestsellers. Our production facility overseas and in the US allows us to deliver premium quality at a price point that makes bulk ordering genuinely viable.
Not only do we keep prices competitive, we keep quality uncompromising. Every garment passes through a dedicated quality assurance inspection before packaging. Our in-house customization services — including screen printing, digital DTG printing, sublimation, and custom embroidery, mean you never have to coordinate with multiple vendors. We are a true one-stop t-shirt manufacturing company for brands that want speed, quality, and reliability in a single partner.
Why Choose Sigma Apparel as Your T-Shirt Manufacturer?
Choosing the right t-shirt manufacturer is one of the most important decisions your brand will make. At Sigma Apparel, we pair you with a dedicated account manager who stays with your project from the first inquiry through to final delivery. Our design team creates detailed mockups and tech packs, covering fabric, color, sizing, measurements, and construction, before a single piece goes into production. This eliminates surprises and ensures the finished garment is exactly what you envisioned.
What separates us from other custom t-shirt manufacturers in the USA is our combination of low minimums, full customization, and complete transparency. Our MOQ of 100 pieces means you are never forced to over-order to get quality production. Our 30 to 35 business day standard turnaround — with physical samples ready in 15 days, means you can move from concept to market faster than most of our competitors. And because we manage production in-house rather than outsourcing to third-party factories, you always know exactly where your order stands.
We currently serve clients across the United States, United Kingdom, Canada, Australia, UAE, and Europe. Whether you are a first-time brand founder ordering your debut collection or an established wholesale buyer placing a 50,000-unit reorder, Sigma Apparel applies the same standard of care to every project. Our goal is not just to manufacture your t-shirts, it is to be the long-term manufacturing partner that helps your brand grow.
The Sigma Apparel
OUR PROCESS
Fabric Selection
Your dedicated project manager guides you through our fabric library — 100% cotton, cotton/polyester blends, performance polyester, organic cotton, and more. We advise the best GSM weight and composition for your style and target market.
Cut & Sewing
Once fabric is confirmed, our skilled production team cuts and assembles each garment to your approved tech pack specifications — ensuring accurate sizing, seam alignment, and consistent construction across every unit.
Customization
All printing and embellishment is handled in-house: screen printing, digital DTG, sublimation printing, custom embroidery, or heat transfer vinyl. We match Pantone colors and run test prints before touching bulk production.
Labeling
Every garment is fitted with your custom label — woven neck label, printed inside label, or hangtag — exactly as per your brand guidelines. We also offer size label, care label, and country of origin label placement.
Packaging
Finished garments are inspected, steam-ironed, folded, and packed to your exact packaging specification — polybags, tissue paper, retail boxes, or hanging tags. Your product arrives shelf-ready.
Shipment
Orders are shipped directly to your address via DHL, FedEx, or sea freight depending on your timeline and budget. We provide full tracking from our facility to your door and follow up to confirm successful delivery.
