Frequently Asked Questions — Oversized T-Shirts Manufacturer in Portugal
Direct technical and operational answers on fabric specifications, certifications, custom branding, and production lead times.
What are the minimum order quantities for oversized t-shirts in Portugal?
Our order quantities are customized for each project. We adjust minimums based on your chosen GSM weight, custom dye lot size, and printing or embroidery details.
What fabric weights can you knit for streetwear tees?
We specialize in heavyweight single jersey and interlock fabrics ranging from 220 GSM up to an ultra-heavy 320 GSM.
How do you prevent the collar from stretching out over time?
We knit our collars with a 1x1 heavy gauge rib incorporating 5% elastane, calculating precise rib-to-neckband tension so crewnecks lie completely flat after 50+ wash cycles.
Can you execute custom pigment washes and acid washes?
Yes. We offer garment dyeing, cold pigment wash, acid wash, vintage enzyme stone washing, and custom distressed edges.
What printing and embroidery techniques do you offer?
We provide water-based screen printing, discharge prints, high-density puff printing, silicone transfers, and 3D chain-stitch embroidery.
