Zegna began in 1910 as a wool mill founded by Ermenegildo Zegna at Trivero in the Biella district and has grown into a vertically integrated luxury menswear house headquartered in Milan. Its knitwear centres on the Oasi Cashmere programme, launched in 2022 with a full-traceability commitment, and extends to vicuña. The label became simply ZEGNA in 2021 alongside the group's New York listing.

How to judge Zegna quality
- For cashmere pieces, look for a stated micron count or grade, 2-ply yarn for sweaters, and a dense knit with no daylight through plain areas. See the cashmere grading guide.
- Merino quality depends on micron (extra-fine is under 18.5 µm) and on worsted spinning; fine-gauge pieces (21–30 gg) are a technical speciality worth paying for.
- Genuine vicuña carries CITES-compliant labelling identifying origin; it is usually undyed and priced in the thousands.
- This house knits fully-fashioned: check for fashioning marks along the armhole and flat, linked seams inside — the signatures of shaped, stitch-by-stitch construction.
