Starting a clothing brand or sourcing workwear for your business comes down to one critical decision: finding a manufacturer you can actually trust. At The Sigma Apparel, we have spent years building that trust with brands across the United States and beyond, one order, one sample, one perfectly produced garment at a time.
Whether you are a first-time founder with a design and a dream, or a business owner who needs hundreds of branded uniforms for your team, here is everything you need to know about who we are and what we do.
A Custom Apparel Manufacturer Built for Brands of Every Size
Sigma Apparel is a full-service custom apparel manufacturer. We work directly with startups, independent designers, growing fashion brands, and B2B businesses who need custom-manufactured garments produced to their exact specifications.
What sets us apart is our minimum order quantity of just 100 pieces per design. That number exists because we believe every brand, not just the ones with deep pockets, deserves access to professional manufacturing, quality fabrics, and a reliable production partner.
What We Manufacture
We are a true one-stop shop. Our production capabilities cover two major verticals:
Custom Fashion & Lifestyle Apparel
From everyday staples to the more specialized pieces that define a collection, we manufacture across the full range:
- Custom T-shirts — all cuts, weights, and fits from crew neck to oversized
- Hoodies and sweatshirts — pullover, zip-up, fleece-lined, cropped, and oversized styles
- Custom jackets — bombers, denim, varsity, puffer, and windbreaker
- Jeans and denim — custom cuts, washes, and hardware

- Custom hats and headwear — snapbacks, beanies, dad hats, trucker caps, and bucket hats
- Leggings — high-waist, printed, compression, and yoga styles
Industrial Workwear & Uniforms
We are one of the very few custom manufacturers that also serves the B2B workwear market — making us the partner of choice for businesses that need durable, branded, and safety-compliant garments:
- Industrial coveralls and overalls for construction, automotive, and chemical sectors
- Flame-resistant (FR) clothing for oil and gas, electrical, and welding environments
- High-visibility (hi-vis) workwear compliant with ANSI/ISEA 107 safety standards
- Custom work shirts and trousers with reinforced construction and multi-pocket designs
- Full corporate uniform programs for hospitality, logistics, retail, and manufacturing businesses
Printing, Embroidery & Fabric Services
- Screen printing — bold, vibrant designs built to last as long as the garment
- All-over sublimation printing — full-coverage photographic-quality prints, no cracking or fading
- Custom embroidery — the premium finish for logos on shirts, hats, jackets, and bags
- Fabric dyeing — garment dyeing, piece dyeing, and tie-dye effects
- Garment washing — stonewash, enzyme wash, acid wash, and distressed finishes
- Custom fabric knitting — develop fabrics from scratch to your exact GSM and composition
How Our Process Works
We designed our process to take the stress out of manufacturing — especially for brands doing this for the first time.
Step 1 — Inquiry: Send us your designs, reference images, or even just a concept. We respond within 24 hours on business days.
Step 2 — Tech Pack & Mockup: Before anything is produced, we prepare a full tech pack covering measurements, colorways, fabric specs, and a digital mockup. You approve every detail upfront.
Step 3 — Sample Production: We produce a physical sample and ship it to you. Review the fit, quality, and finish — we do not move to bulk until you are fully satisfied.
Step 4 — Bulk Production: Sample approved? Production begins. Standard bulk lead time is 15–20 business days after sign-off.
Step 5 — Quality Check & Delivery: Every order is inspected before it ships. Our Logistics do have full tracking, so you always know where your order is.

- Full transparency from day one — tech pack, mockup, and sample before any bulk commitment
- Complete design security — your intellectual property is never shared or reproduced
- Single point of contact from inquiry to delivery — no chasing multiple vendors
- Both fashion apparel and workwear under one roof — rare in the manufacturing space
- 30–35 business day turnaround keeping launches and business timelines on track
- US office for easy communication with North American clients
Frequently Asked Questions
What is The Sigma Apparel’s minimum order quantity?
Our MOQ is 100 pieces per design and color. This applies across all product categories — t-shirts, hoodies, activewear, workwear, and everything else we manufacture.
Do you manufacture both fashion clothing and workwear?
Yes, and this is one of the things that makes us unique. We manufacture everything from custom streetwear and activewear to industrial coveralls, flame-resistant clothing, and full corporate uniform programs. If it is a garment, we can make it.
Can I order a sample before committing to bulk production?
Always. Every order includes a sampling phase. We produce and ship a physical sample for you to review and approve before we begin bulk manufacturing. No bulk order ever starts without your sign-off.
How long does production take?
Our standard turnaround is 30–35 business days from sample approval — approximately 15 days for sampling and 15–20 days for bulk production. We can discuss expedited timelines for urgent orders.
What customization options do you offer?
We offer screen printing, all-over sublimation printing, custom embroidery, fabric dyeing, garment washing, custom labels, and custom packaging. If you can design it, we can produce it.
What fabrics and materials do you work with?
We maintain a large inventory of readily available fabrics and can also knit custom fabrics from scratch to your exact GSM and composition. We source performance fabrics, organic cotton, FR-rated materials, recycled fibres, and more depending on your product requirements.
