The Heavy Weight Champion T-shirt puts the finishing touch to our wardrobe: a selection of timeless items that we make here at our workshop in the Aveyron region.  The name speaks for itself: like the greatest boxers, it is elegant, agile, and incredibly strong, thanks to the GOTS-certified Oeko-Tex® organic cotton with an interlock knit.

Every t-shirt, meticulously woven by a hundred-year-old family-run business in the Somme, is a reflection of centuries-old skills that have been passed down through the generations. Made from organic cotton interlock fabric, the Bleu de Chauffe T-shirt seamlessly combines comfort and respect for the environment. Assembled with care at our workshop in St Georges de Luzençon in the Aveyron region, it embodies our commitment to quality and comfort, and is locally made from weaving right through to assembly.

More than just a piece of clothing, the Bleu de Chauffe t-shirt is a timeless item that combines quality, artisanal skill, and environmental responsibility. 

Knit and made in France

For the design of our Bleu de Chauffe T-shirt, we decided to opt for an interlock knit. We had this interlock knit made by a family business founded over a century ago in the Somme (Northern France), renowned for their skill and with whom we share common values.

Détails :

- 100% GOTS-certified organic cotton with Oeko-Tex® label, interlock knit. Interlock is a double-stitch knitting technique that makes a more sturdy, denser weave: you could call it ‘double-texture’

- The Heavy Weight Champion comes in at 250g/m²

- Cut : slightly wider at the sleeves and the chest

- Round-neck T-shirt. Double-thickness folded collar.

- Discreet label at the bottom, proof of the authenticity of this product

In its ecru shade, our T-shirt reflects the natural color of the fiber. Slight irregularities may appear in this natural, undyed material, adding subtle depth and preserving its authenticity.

Care : 

- Wash at 30°.

- Do not tumble dry

- Turn before washing

Heavy Weight Champion, top of its class


By choosing this name, we're highlighting the exceptional strength and durability of our T-shirt, making it the undisputed champion in its category. This choice subtly evokes the world of wrestling and combat, referring to the best in their discipline. Much more than just a name, the Heavy Weight Champion embodies the quintessence of solidity. Its quality and weight make it much more than just a T-shirt. With that in mind, we've selected what we believe to be the best materials to bring you an experience steeped in craftsmanship.

This T-shirt is not produced on the other side of the world, but knitted in the Somme and assembled in our workshop in Saint-Georges-de-Luzençon. Our aim was to create a product with impeccable ethics, reflecting our commitment to quality and sustainability.

Knit for flawless quality: interlock


Interlock is a complex knitting technique that offers unparalleled density and feel. Due to the higher cost of this knitting method, jersey is often preferred over interlock, so it's rare to find interlock T-shirts

Unlike conventional jersey, interlock is characterized by a double knit construction that forms a denser, tougher structure that can be described as double-contextured. This unique construction offers superior dimensional stability and a smooth, even surface, providing a soft, comfortable feel inside and out that is unparalleled when worn and in contact with the skin. The thicker structure gives the fabric greater durability, ensuring better wear over time and resistance to deformation and abrasion, even after many washes and uses.

Interlock and the Heavy Weight Champion T-shirt offer a unique experience that combines comfort, durability and elegance that you'll feel the moment you take it out of the package and wear it every day.

The cotton used in our T-shirts is knitted in the Somme region of France by a century-old family business with recognized expertise.

Every stitch, every finish is carried out by our artisans, who are passionate about their craft, ensuring the impeccable quality of each piece.

The studied cut of the Heavy Weight Champion T-Shirt 


Inspired by workwear styles, our T-shirt also looks great with more elegant outfits. We've chosen a slightly loose fit in the sleeves and bust to create a harmonious silhouette no matter what your body type. The length of the sleeves has been adjusted to allow for a variety of styling options, including rolled sleeves. Meanwhile, the collar is designed not to be too tight for optimal comfort.

We've paid special attention to details such as the double-needle turned-in ribbed hem, which adds a subtle touch of elegance to our T-shirt. What's more, a discreet label guarantees the authenticity of our product, which bears the Bleu de Chauffe, Saint-Georges-de-Luzençon label.
