Extra Heavy Cotton T-Shirt / Long-Sleeve
Extra Heavy Cotton T-Shirt / Long-Sleeve
Our heaviest T-shirt with a refined yet relaxed expression: this Long-Sleeve is a true everyday favorite.
Made from 100% organic cotton, the Long-Sleeve Extra Heavy Cotton T-Shirt boasts almost double the weight of our medium-weight Cotton T-Shirt. This structured hand feel is reflected in wider ribs on the neckline and hem, resulting in a well-balanced look. At 280 g/m2, it has a sculptural drape that’s universally flattering.
Your Long-Sleeve Extra Heavy Cotton T-Shirt is made to order, made to fit, and made to last in Portugal.
Details
EXTRA HEAVY COTTON T-SHIRT L/S
Durable yet soft. The Extra Heavy Cotton Long-Sleeve T-Shirt is our most durable long-sleeve – dense, structured, and ready for the outdoors. It pairs the reassuring weight of 280 g/m² cotton with the quiet sophistication that defines SON essentials.
PURPOSEFUL FIT
Subtle refinement in fit and sleeve pitch ensures movement without bulk. Built for cooler days, it’s a piece that wears beautifully across seasons and years.
BUILT FOR LONGEVITY
Crafted from 100% organic cotton in a 280 g/m² heavy jersey that balances rugged durability with unexpected softness. The dense weave gives structure while remaining comfortable next to skin.
ARCHITECTURAL SHAPE
The fabric’s thickness produces a natural, architectural drape – it stands slightly away from the body while allowing air to move freely, giving both presence and comfort.
Material
Organic Cotton
Organic cotton makes up less than a quarter of the world’s cotton, yet it stands apart for the way it is grown and worn. Free from synthetic pesticides and fertilizers, it is softer on the planet, naturally breathable, and strong enough for everyday use in both lighter and heavier weights.

Production
PNEM
Small but vital, PNEM supports the foundation of our production – cutting and coordinating the making of our white Supima T-shirts. The company is run by Eduardo, one of our longest-standing collaborators, whose expertise has shaped how we produce today.
Quality Check
Every Son of a Tailor garment is carefully inspected by hand before it leaves our production floor. Our team checks each piece for fit accuracy, finishing, and overall quality, ensuring you receive exactly what you ordered, and nothing less.
This final step is more than a formality; it’s a promise. By keeping this process in-house, we guarantee every T-shirt, sweater, and hoodie meets the standards we set for ourselves. No shortcuts, no compromises – just honest craftsmanship checked by the same people who made it.
Shipped Directly
Unlike most clothing brands, we manage not only our production but also our logistics, meaning your garments travel as quickly as possible from our hands to yours.
By handling fulfilment internally, we eliminate unnecessary middlemen and reduce errors. The result is a simpler, faster, and more reliable process – one that mirrors the precision of how our products are made. It’s a small detail that makes a big difference in ensuring every order arrives exactly as intended.
End to end Production
In 2022, we established SON Supply, our own production facility in Santo Tirso, Portugal. Today, over 55% of our garments are made there, with the rest produced by a tightly knit community of trusted artisans across the country.
Together, they share our commitment to quality, precision, and sustainability. From cutting to knitting, sewing to packaging, every step happens under our supervision. We take pride in doing the hard work ourselves – creating products made for you, made to order, and made to last. This is what end-to-end craftsmanship looks like.
Service
Whether you’re ordering your first T-shirt or you’ve been with us for years, we take the time to make sure you get exactly what you need. If something isn’t right, we fix it. Our team is easy to reach and empowered to help.
