Peter Millar Marks 25 Years With Ultra-Rare Vicuña Collection

The American menswear house celebrates its silver anniversary with an exceptionally limited release crafted from one of the world’s finest natural fibres.

Peter Millar is entering a new realm of luxury. To commemorate its 25th anniversary, the North Carolina-founded brand has unveiled an exclusive collection of just 25 vicuña jackets and zip-front cardigans.

Priced at $6,995 and $4,995 respectively, the pieces are made from an extraordinarily rare fibre sourced from wild vicuñas in Peru. Unlike alpacas and llamas, vicuñas cannot legally be farmed. Their fleece is gathered under tightly regulated conditions designed to protect both the animals and the future of the species.

The centuries-old Peruvian tradition known as the chaccu remains central to the process. Communities form an expansive human chain to guide wild herds into temporary enclosures, where each animal is carefully shorn before being released. Because a vicuña needs time to regrow its insulating coat, its fibre can be collected only once every two or three years.

That scarcity is matched by remarkable softness. Vicuña fibres measure approximately 12.5 microns in diameter, compared with around 15.5 microns for fine cashmere. The difference may appear slight, but it creates a noticeably lighter, smoother and more refined handle.

The anniversary collection also represents something of a homecoming. Peter Millar began in 2001 with a single product: a richly coloured cashmere sweater. The company subsequently built its reputation on polished sportswear, performance fabrics and comfortable tailoring, becoming particularly familiar to golfers through its signature polo shirts.

Its ambitions continued to grow. Peter Millar opened boutiques in the Hamptons and Palm Beach in 2011, before joining Swiss luxury group Richemont the following year. The acquisition placed the brand alongside celebrated maisons and watchmakers including Chloé, Dunhill, IWC, Jaeger-LeCoultre and Vacheron Constantin.

For autumn 2026, that elevated approach extends beyond vicuña. The wider collection includes a double-faced cashmere peacoat, knitwear made from exceptionally fine Italian baby cashmere—described by the brand as “First Fleece”—and a vest fashioned from New Zealand deerskin.

Yet Peter Millar’s evolution is not simply an exercise in opulence. Under chief creative officer Jason Cater, the emphasis remains on clothing that feels relaxed and effortless, however exceptional its materials may be.

The result is a quietly confident expression of contemporary luxury: rare without being ostentatious, sophisticated without sacrificing comfort, and grounded in the tactile pleasure of extraordinary craftsmanship. For a company founded with one cashmere sweater, vicuña feels like a fitting way to celebrate its first quarter-century.
