Undoubtedly, wool is the best material for men’s suits. That is because wool has several characteristics that are very suitable for the human body.
Wool acts as an insulator so it is very warm. Wool absorbs and releases moisture quickly and in this way allows the fabric to “breathe”. It is dirt resistant, flame resistant, and, in many weaves, resists wear and tear. Wool garments do not soil easily and they do not need to be cleaned after every use.
There are some types of wool, each of them being very suitable for a men’s suit: Alpaca Fleece, Angora, Cashmere, Mohair, Camel Hair, Virgin Wool, Boiled Wool.
More benefits of the wool are that it is durable, naturally wrinkle resistant, fire retardant, colorful, naturally non-allergenic, renewable and sustainable.
Laboratory tests have shown that wool fibers resist tearing and can bend back on themselves more than 20,000 times without breaking. Wool clothing will last for years and clean easily, because wool resists spills, dries very quickly and is mildew resistant.
Naturally wrinkle resistant, really? Yes, wool fabrics resist wrinkles. Wool is the most resilient fiber because wool fibers can be stretched and still bounce back to their original shape.
Wool has natural fire-retardant properties. It can resist flame without the chemical treatment involved in fireproofing.
Wool is naturally colorful, since there are a great variety and number of breeds of sheep that come in a wide array of colors. In addition, the structure of wool fibers allow wool to easily accept dyes without the need for harsh and sometimes toxic chemicals to prepare the fiber for dyes.
Wool is almost entirely non-allergenic.
The best thing is that wool is renewable and sustainable. It can be shorn from sheep annually. It is biodegradable and kinder to the environment than oil-based synthetics, which contribute to global pollution. Yes, wool is sustainable.
When selecting a suit you see at the tag  Super 100’s or Super 150’s, the number represents the number of times the worsted wool has been twisted. The higher the number, the finer and lighter the cloth will be.
Today producers are able to yield fleece that reaches the heights of 200s. The higher Super count means that the fabric has a smoother texture and appear more luxurious. Sub 100s range is a hardy fabric that will last for generations. Past 140s the fibres are too fine, tend to wear easily and require spot cleaning.
Some producers offer fabrics from wool blends, which can also be a good solution, because you get the benefits of both fabrics.
Never choose a suit made entirely of polyester or other synthetic materials.
The best fabrics in the world are italian and british fabrics. So if you choose an italian suit, you will not make a mistake. If you get a bespoke or made-to-measure suit you will be able to select the fabric yourself. So, you need to know the names of the best fabric brands in the world, among which are  Vitale Barberis Canonico (VBC), Holland & Sherry, Ermenegildo Zegna, Loro Piana, Cerruti, Dormeuil, Harris Tweed etc.
You can see all those fabric brands on trade fairs in Europe like Pitti Uomo in Florence, Milano Unica in Milan and Premiere Vision Paris.
