WATC Studio is a European blank maker that says its garments are crafted in its own ateliers in Portugal. Its pitch is weight and fiber: every tee and hoodie listed here is 100% cotton that the brand describes as organic, and the weights start where many brands' heavy styles stop. The site sells tees, hoodies, quarter-zip sweaters, sweatpants, sweatshorts, cargo pants and denim, and it advertises business services for labels that want more than a stock blank.
Weights in GSM
WATC lists fabric weight in GSM, grams per square meter. Its tees are 240 GSM, roughly 7.1 oz/yd² by conversion, which puts them in heavyweight territory. The standard hoodies are 460 GSM French terry, and the Ultra Heavy line reaches 860 GSM for a single layer of fabric.
Product pages also show an ounce figure and a kilogram figure next to the GSM. Those two numbers match each other and change with the cut, so they read as the weight of the whole garment rather than of the fabric. When you compare WATC with a brand that quotes oz/yd², convert the GSM and ignore the garment weight. What is GSM in fabric shows the conversion.
Cuts
The tees come in three shapes on the same jersey: Regular, Oversized with dropped shoulders, and Oversized Boxy, which is the widest and squarest. The hoodies follow the same logic, with an Oversized cut and an Oversized Boxy cut that is cropped in length. Everything is unisex and sized XS to XXL. A boxy, cropped body changes how large a print can be and where it sits, so check the size chart against your artwork; boxy, oversized and streetwear fits walks through placement on these shapes.
Ribbing on the collars and cuffs carries a small share of Lycra for recovery. Rib stretches and rebounds, so keep prints off the collar and cuffs.
Decorating heavy organic cotton
All-cotton jersey at this weight is an easy base for screen printing. Plastisol sits on top without the fabric showing through, and water-based or discharge inks work on cotton as long as the dye responds, which only a test on the actual color will tell you. With no polyester in the body, dye migration from the fabric into light ink is not the usual worry. DTG also suits 100% cotton; the dense knit gives a firm surface once pretreated.
The French terry hoodies print on their smooth knit face, the same as fleece, and the looped back stays inside. Very heavy fabric changes the job in two practical ways. It soaks up heat, so the printer may need more dryer time to cure ink all the way through. And it is thick in the hoop, so embroidery on the 860 GSM pieces needs a frame that can close on that much fabric and an embroidery backing chosen for it. Neither is a reason to avoid the style, but both are worth raising at the quote stage. French terry vs fleece explains how the two hoodie fabrics differ.
Untagged necks and private label
WATC lists its tees and hoodies as untagged. With no maker's label to cut out, you can add a printed inside-neck label or a sewn woven label and sell the piece as your own private label product. Private label finishing covers what a replacement label should say, including fiber content and country of origin.
On the organic claim: it describes the fiber, as stated by WATC. If you want to call your finished product organic, ask the brand what certification sits behind the cotton, and treat inks, labels and trims as separate questions.
Choosing a WATC style
- A heavy tee with a conventional shape: the Regular Tee.
- Relaxed drape for streetwear: the Oversized Tee.
- Maximum print width and a square look: the Oversized Boxy Tee.
- A heavy hoodie that most customers will size easily: the Oversized Hoodie.
- A short, wide hoodie: the Oversized Boxy Hoodie.
- A statement piece where weight is the point: the Ultra Heavy Oversized Hoodie.
Alternatives
AS Colour also sells heavy, boxy cuts, and Blanks by Thirteen makes all-cotton fleece in the US. Heavyweight vs midweight vs lightweight T-shirts puts 240 GSM in context against other tees.
