Shaft Jeans garments are made in Italy, and the brand markets itself as "100% Made in Italy." Production is described as taking place between the company's Florence headquarters and manufacturing facilities in Italy's Marche region, with garments "entirely sewn in Italy." The newer Shaft Pixel digital-print line is also described as a "100% Made in Italy" process.

Shaft Jeans is a family-owned Italian denim brand, not part of a large parent conglomerate. The brand was originally founded in Montpellier, France in the 1960s by a French craftsman referred to as "Monsieur Shafir" (the brand's own materials give the founding year inconsistently as both 1964 and 1968, and the homepage strapline reads "Denim Authors since 1968"). It arrived in Italy around 1968. Shaft Jeans was acquired in May 2004 by Florentine entrepreneur Francesca Bacci, who runs it through her Florence-based company Manifatture Twins (Srl); she previously spent 20+ years in a family business that produced garments from American Cone Mills denim. Shaft Jeans is today managed by Bacci together with her twin children, Letizia (joined 2015, style/sales) and Lorenzo (joined 2020, production/finance), who in an interview are named Letizia and Lorenzo Palchetti Tosi. It remains an independent, privately held company.

Shaft Jeans is a real, currently-trading legitimate business. It maintains an active e-commerce site (shaftjeans.it), released an Autumn/Winter 2025 collection (including a "Leather Effect" denim and the "MIA" capsule), launched its Shaft Pixel digital-print jeans in Milan on 28 February 2025, opened a second monobrand store in Milan (Corso Magenta 22) in February 2024, and is stocked by multiple independent retailers (e.g. Boyds Philadelphia, Aqualta, Marina Lari, Avalon Clothing) and on Lyst. It is the Italian denim/clothing brand, distinct from same-name entities in other fields.

Shaft Jeans is a slow/small-batch premium brand rather than fast fashion. It positions itself as a Made-in-Italy premium denim label sold "only in high fashion stores and boutiques," works to a seasonal collection model (an interview describes roughly 20 collections of about 100 pieces each with 10+ fittings before approval), and prices garments at a premium level (the Shaft Pixel jean debuted at about €349 in Italy and €437 internationally). Its volumes, boutique distribution, Italian craftsmanship and price point are inconsistent with a fast-fashion operation.

Certifications: Shaft Jeans does not publicly document any verified third-party certification (no GOTS, OEKO-TEX, Fair Trade, B Corp, or European Flax certificate/number is displayed on its website). The brand sells an "Organic" line and states its organic cotton is grown without pesticides, heavy metals, resins or solvents, but the official site backs this with proprietary process names rather than certification marks. In one third-party interview (The Italian Rêve) the founders described a "GOTS certified" organic denim line, but this single interview mention is not independently verifiable against a certification body or a certificate shown on Shaft's own site. Treat any GOTS claim as unverified. No OEKO-TEX, Fair Trade, B Corp, or European Flax certification could be confirmed..

Shaft Jeans does not publicly document a recognised textile certification such as GOTS or OEKO-TEX in the sources we checked.
