The time has come to legitimize the Solaro suit as a staple garment in any man’s wardrobe.

Oh please, don’t give me that look. We already established a long time ago that brown and earthy colors are no longer reserved for the countryside, and we integrated them as part of our daily – and even business – clothing. A Solaro suit is going to be your best investment this summer.

First, let’s go back to the origins of the fabric. Despite being quite popular among the Italians, we owe the invention of Solaro to the Brits and their assumption that the red color repelled radiation caused from direct sunlight.

The Solaro was born at the dawn of the 20^th century, during the colonialism of the Tropics. The London School of Tropical Medicine dedicated studies to the wellbeing of the soldiers in colonial lands: climate conditions in tropical areas were incredibly harsh, and a need for new fabrics and garments to protect the colonizers arose as it did the belief that they were responsible for dreadful tropical diseases.

One of the School’s scientists, Louis Westenra Sambon, conducted some studies on the skin of the colonized populations, coming to the conclusion that the darker pigment was able to block off the UV rays coming from the sunlight. It was clear to him that Nature provided the natives with the necessary protection against the harm of the climate, and that the colonizers would have had to find a way to protect their fair skin just as well. Clothes were the obvious choice, as they act as an additional layer to protect the body from the external agents.

It was common knowledge at the time that light fabrics retained less heat than dark fabrics; however, white garments were not quite suitable for soldiers. Khaki green, on the other hand, was both light and suitable for a soldier’s uniform, and that’s why Dr. Sambon chose it as the base of the cloth of his invention: the Solaro. He added to it a red layer that supposedly repelled the UV rays.

“Dr. Sambon, assisted by Mr. John Ellis, has produced a fabric hat has a “perfect khaki effect” on the outside and a red colour screen on the inner surface, and he has stated that Mr. Bailey has examined it at the University College and that it has proved as impervious to the actinic rays as is the skin of natives of tropical countries. This cloth is called Solaro. We have not seen specimens of this cloth, but we note that it is obtainable at Messers Ellis and Johns, Tailors, 21, South Moulton Street, London, W.”¹

“Unlike clothing promoted for use in tropical climates today, Solaro was meant to prevent more than sunburn and carcinomas. It was designed to inhibit the “actinic” rays—what we would now call ultraviolet (UV) radiation—of the sun, which were thought to disrupt proper physiological functioning and produce nervous disorders. The design of the clothing was linked to the observation that skin color was darkest where sunlight was most intense.”²

Another debate concerned the type of fabric that would work best against the heat: cotton or wool? German zoologist Gustav Jaeger pointed out that many animals survive in tropical areas with a wool coat, and that wool breathes better than vegetable fabrics, which are not meant to be used in clothing: “Nature has clothed the animals. Man clothes himself. Animal wool, which Nature has created to clothe the animal body, is the ‘survival of the fittest’ clothing material.”³

His assumption is at the base of Dr. Sambon’s choice of wool for the Solaro.

The patented Solaro fabric –“Original Solaro Made in England”- is produced by Smith Woollens (now part of Harrisons). It weighs 310 gr and is in a tan/olive-ish color with a herringbone pattern. It features an underside woven with brick red yarn;

this characteristic produces an iridescent sheen that is most evident when the light hits the fabric at a specific angle, but it is nonetheless quite subtle.

Today there are several mills – Loro Piana, Drago, Angelico, to name a few- that produce Solaro in a variety of weights and hues, yet remaining somewhat faithful to the mid-weight, khaki-and-red original version.

The most common fabrics employed to create Solaro are pure wool twill and yarn-dyed gabardine.

As I mentioned, the Italians are particularly fond of Solaro suits, as they embody perfectly the Italian sprezzatura with the relaxed, casual, and slightly impudent look provided by the semi-iridescent cloth. It’s not uncommon to spot distinguished, elderly Italians wearing Solaro suits, whether they are businessmen riding a bicycle in Milan, or classy Neapolitan gentlemen savoring espresso at a café while reading the Corriere della Sera.

Here are a few good reasons why a Solaro suit is the perfect integration to your summer closet:

– It’s a conversation starter; we are not given that many chances to make fun of the Brits (if we don’t consider Brexit) so why lose the chance to make a joke of their belief that a red thread in their suits would keep them safe from tropical diseases? Jokes aside, the history of the fabric and its continental charm make a good topic of conversation for anyone who has an interest in menswear or history.

– It’s unconventional but not crazy extravagant; the red sheen is barely there, just enough to remind the world that you are confident enough to pull off a suit that goes beyond the conventions. You own it.

– It suits everyone. Just take look at the gallery, and you’ll see that a solaro suit looks good on every single person, flattering every complexion from the fairer to the deeper. Additionally, it seems to class-up everyone’s style, making the solaro suit the male equivalent of a pearl choker.

– It makes a great option for business casual. I promise not to roll my eyes and scoff when you tell me that America is too conservative to allow such a suit to be part of a business environment. However, to the West Coast fellows that suffer from suit envy because their workplace is too casual to wear even the most innocent two-piece navy suit, I say: this is your chance! A Solaro suit is casual enough to be worn even in an office where the most formal piece of clothing is not-ripped denim, and you won’t be labeled as “the uptight dude in the navy suit”. Plus, you can lose the jacket any time and not look like you forgot a piece of your outfit at home.

If you’d like to read what other forumites have to say on the matter, there is a whole thread dedicated to wearing Solaro for business.
