Why Portugal
Why Manufacture Sweatshirts in Portugal?
Portugal is one of the strongest sweatshirt manufacturing bases in Europe. The northern textile belt around Porto and Barcelos has specialised in fleece and French terry production for decades, with a supply chain that extends from yarn spinning and knitting mills to cut-and-sew factories and finishing houses — all within a 50-kilometre radius. This concentration means faster turnarounds, tighter quality control, and better pricing than sourcing each stage from different countries.
For sweatshirt production specifically, Portuguese mills excel at heavy-knit fabrics. French terry and brushed fleece at 400+ GSM require specialised circular knitting machines and precise brushing processes — skills that are commonplace in this region but rare in lighter-fabric markets. When you source sweatshirts from Portugal, you are tapping into factories that produce heavyweight fleece every day, not as a sideline.
All our sweatshirt fabrics are OEKO-TEX certified, with GOTS-certified organic cotton options available. EU manufacturing standards govern every stage — from dye chemistry to wastewater treatment. For brands selling into the European market, this means no customs delays, no import duties, and full traceability from fibre to finished garment. Your customers can verify the origin and certification of every crewneck you sell.
Our minimum order quantity is 50 units per style and colour — one of the lowest in European sweatshirt manufacturing. This makes it practical for emerging brands to produce custom crewnecks, half-zips, and oversized sweats without committing to the 500+ unit minimums typical of larger factories. Start small, prove the design, then scale with the same manufacturer.

Fabrics for Sweatshirt Manufacturing
Choosing the right fabric is the most important decision in sweatshirt manufacturing. French terry is the year-round standard — lighter and more breathable with soft loops on the inside. Brushed fleece is the heavyweight choice for winter collections — warmer, softer, and denser. Polycotton fleece is the practical option for volume orders — less shrinkage and better colour retention at a lower cost.

From Idea to Delivery
How It Works
Send Your Design
Share your sweatshirt tech pack, sketches, or reference images. Tell us about fit (regular, oversized, cropped), fabric preference (French terry, brushed fleece, polycotton), GSM target, and decoration. We accept designs at any stage — from a rough concept to a full specification sheet.
Receive Quotation
Within 48 hours, you receive a detailed quotation covering fabric, trims, decoration, and production — broken down per unit. No hidden costs. We include fabric swatch options so you can compare French terry vs fleece weights before committing.
Approve Sample
We produce a physical sample for your approval. You review fit, fabric weight, collar ribbing, cuff tension, and decoration quality. Adjustments are included — we iterate until the sample matches your vision. Most sweatshirt samples take 1–2 weeks.
Full Production
Once you approve the sample, production begins. We handle cutting, sewing, finishing, decoration, quality control, labelling, and packaging. Standard production takes 4–6 weeks. You receive progress updates and your finished sweatshirts are shipped directly to your warehouse.
Common Questions
Frequently Asked Questions
What is the best GSM for crewneck sweatshirts?
For standard crewneck sweatshirts, 320–400 GSM provides a solid, quality feel without excessive weight. Lightweight summer crewnecks work well at 280–320 GSM. For premium heavyweight crewnecks — the thick, structured feel popular in streetwear — 400–500 GSM is ideal. Ultra-heavyweight options at 500–580 GSM deliver a very dense, rigid garment suited to oversized cuts. We help you choose the right GSM based on your brand positioning and season.
What is the difference between French terry and brushed fleece for sweatshirts?
French terry has a smooth face on the outside and soft, uncut loops on the inside — it is lighter, more breathable, and suited for year-round wear. Brushed fleece has those interior loops mechanically brushed into a dense, velvety nap, making it heavier, warmer, and softer to the touch. For summer or transitional crewnecks, French terry is the better choice. For winter heavyweight sweats, brushed fleece delivers superior warmth and a more luxurious hand feel.
Can you manufacture oversized sweatshirts?
Yes. Oversized and boxy cuts are one of our most requested sweatshirt styles. We produce dropped shoulders, extended body lengths, and wider silhouettes in both crewneck and half-zip formats. Oversized fits work best in heavier fabrics (380–500 GSM) to maintain the structured drape without looking shapeless. We develop custom patterns to your exact measurements — we do not simply grade up a regular-fit pattern, which would distort proportions.
Can you embroider on sweatshirts?
Yes — embroidery is one of the most popular decoration techniques for sweatshirts. We run multi-head Tajima machines capable of up to 15 colours per design. Common placements include left chest logos, centre chest, back yoke, and sleeve branding. For heavyweight fleece (400+ GSM), we use cut-away stabiliser backing to prevent puckering. We also offer 3D puff embroidery for raised, textured logos that stand out on crewneck sweatshirts.
Can you produce matching sweatshirt and jogger sets?
Yes. Co-ord sets (matching crewneck or hoodie plus joggers) are a core part of our production. We cut both garments from the same fabric roll to ensure perfect colour consistency — ordering tops and bottoms separately often results in shade variation between dye lots. We produce matching sets from MOQ 50 units per colourway, covering both the sweatshirt and the jogger in a single production run.
What is the minimum order quantity for custom sweatshirts?
Our minimum order quantity is 50 units per style and colour. This applies to all sweatshirt types — crewnecks, half-zips, and oversized cuts. For first orders, we recommend starting with one or two styles to test fit and fabric before scaling. Volume discounts apply for orders above 200 units per style.
What decoration techniques work best on sweatshirts?
Sweatshirts are versatile for decoration. Screen printing works well for chest prints and large back prints — the smooth exterior face of French terry and fleece provides a clean surface. Embroidery is ideal for logos and text — it adds a premium, textured finish. DTG (direct-to-garment) printing handles photographic or multicolour artwork. We also offer puff print, discharge print (for a soft hand on dark fabrics), and appliqué patches for a heritage or varsity aesthetic.
Do you offer half-zip sweatshirts?
Yes. Half-zip (or quarter-zip) sweatshirts are available in all our sweatshirt fabrics. We use YKK or Superba branded zippers with customisable puller options — including metal, rubber, and cord pulls. The zip tape colour can be matched or contrasted to the garment. We produce both mock-neck and standard collar half-zips, and can add kangaroo pockets, side pockets, or clean no-pocket finishes.
