Loro Piana Fabric Guide — Why It's the World's Finest Wool

Among the dozens of names in the world's finest wool production, Loro Piana stands in a category of its own. Founded in 1812 in Quarona, Piedmont, and now operating the most sophisticated wool sourcing and weaving operation in the world, Loro Piana produces fabrics of a quality that must be handled to be believed. This guide explains why, and how to choose the right Loro Piana cloth for your commission at Manhattan Tailors.

The Source: Wool of Extraordinary Fineness

The quality of any wool fabric begins with the raw fibre, and Loro Piana has invested more than any other mill in securing the finest fibre sources in the world. Their story begins with Merino wool from Australia and New Zealand — specifically the finest fleeces from elite Merino studs that produce fibres measuring 11–13 microns (compare with standard Merino at 18–22 microns; human hair is approximately 70 microns). Loro Piana has exclusive supply agreements with the top superfine Merino producers, guaranteeing access to fibre unavailable to other mills.

Their most extraordinary products use vicuna — fibre from the wild vicuna of the South American Andes, which measures approximately 12 microns and is so rare and precious that a vicuna suit cloth costs thousands of pounds per metre. Even more accessible products — the Tasmanian Super 180s, the Four Seasons range — are produced from fleeces in the 14–16 micron range, placing them in the super-fine category that most mills cannot source at all.

Loro Piana's Key Suiting Collections

Tasmanian range: Loro Piana's flagship suiting fabric, made from the finest Tasmanian Merino wool. Available in Super 150s through Super 200s weight counts, with higher numbers indicating finer fibre and lighter weight. The Tasmanian Super 150s is one of the most popular choices for a luxury business suit — fine enough to drape beautifully, substantial enough for year-round wear and robust enough for regular use.

Four Seasons: A lightweight (approximately 250–270g) all-season fabric designed to be worn twelve months of the year in climate-controlled environments. The weave is engineered to breathe in warm conditions and provide warmth in cooler ones — a technically remarkable cloth and extremely popular with international travellers.

Raincoat wool: Loro Piana's fabric treated with their proprietary Storm System water-resistant process, applied to the finished cloth without affecting its handle or breathability. A suit made from Storm System cloth can withstand a light to moderate shower without showing water marks — practically very useful for Hong Kong's wet season.

Handle and Drape: What Sets Loro Piana Apart

What no photograph or description can fully convey is the handle of Loro Piana cloth. Picking up a swatch of Loro Piana Super 150s beside a standard Super 120s from another mill is an education: the Loro Piana is perceptibly softer, cooler against the skin, and its surface has a silky smoothness that comes from fibre fineness rather than finishing treatment. The drape — the way the cloth falls in a suit — has a fluidity and life that is unique to this quality of wool. A jacket made in Loro Piana falls perfectly, holds its shape under a day of wearing and recovers completely when hung overnight.

Pricing and Value

Loro Piana cloth commands a significant premium over standard mill fabric — at Manhattan Tailors, a Loro Piana commission typically adds HKD 4,000–10,000 to the base suit price depending on the specific collection chosen. For clients who wear a suit five days a week, the cost-per-wear difference over five years of daily use is negligible. For clients who wear suits for important occasions and want the very best cloth available, there is simply no alternative at the top of the market.
