Just in time for summer, Bleu de Chauffe debuts a t-shirt that you can wear all four seasons. Their Champion tee is on the heavier weights we’ve seen and much of that is due to the special interlock knit “double-texture” jersey fabric they’ve made specially in France.

Interlocking essentially laces together two separate knits into the same fabric (see last pic below), making for a stronger, softer, and heavier final product. The resulting jersey is about 7.5 oz. of Global Organic Textile Standard cotton, nearly double what you’d see on a standard skivvy.

The specially knit fabric is cut and sewn in house by the artisans at Bleu de Chauffe’s Aveyron workshop into a tee that has slightly longer and wider sleeves for rolling, an open scoop neck, and a double-thick collar for an effortless workwear staple.

The Champion tee is available for $50 in Ecru, Khaki, Mottled Grey, and Navy at Bleu de Chauffe.
