Key Points
01Rain System is Loro Piana’s water-repellent surface treatment, which the brand says it can apply to all its fabrics.
02Storm System adds a waterproof, breathable membrane and a fine jersey layer to that finish, for wind and rain resistance.
03Treat even Storm System garments as protection from showers, not as a fully waterproof shell for long, heavy rain.
04Dry wet knitwear flat and wet coats on a broad hanger, away from radiators and direct sunlight.
Loro Piana clothes cost a great deal, so it is natural to worry about wearing them on a rainy day.
The short answer is that some Loro Piana outerwear is made for wind and rain, while knitwear, silk and leather need protecting.
This guide explains what Loro Piana’s weather treatments are, which garments use them, how to wear the brand’s clothes in wet weather, and how to dry and care for them afterwards.
Loro Piana’s Weather Treatments
Loro Piana describes its weather treatments on its own website, and the two you will see most often on labels are Rain System and Storm System.
Rain System
Rain System is a water-repellent treatment that Loro Piana says it can apply to the surface of all its fabrics, invisibly coating each fibre.
The brand lists it as rain resistant and as protecting cloth from dust, dirt and stains while keeping its normal look.
A water-repellent finish makes rain bead and roll off, but on its own it is not the same as a waterproof layer.
Storm System
Storm System builds on the Rain System finish.
Loro Piana says it combines that water-repellent finish with a hydrophilic membrane that is waterproof, wind resistant and breathable, and a third layer of ultra-fine jersey.
The brand lists it as wind and rain resistant and highly breathable, and says it was developed for unlined garments.
A version called Green Storm System uses the same water-repellent finish with a bio-based membrane.
Treat any of these treatments as protection from showers and a wet commute, rather than as a substitute for a fully waterproof shell in long, heavy rain, because seams, zips and openings also let water in.
Loro Piana does not publish water-pressure figures for these treatments on its systems page, so be wary of any precise waterproof rating quoted without a source.
Loro Piana Outerwear for Wet Weather
The garments below are examples of Loro Piana outerwear that use the brand’s weather treatments, as described on Loro Piana’s own product pages or by its stockists.
The Traveller Jacket
The Traveller is a Loro Piana travel jacket, and its US website spells one current version “Traveler”.
That field jacket is made of polyamide microfibre with a water-repellent and wind-resistant Storm System finish on one side, is lined in cashmere and has a hood that stows in the collar, according to the brand’s product page in October 2026.
It suits city wear in showers and travel, and its cashmere lining makes it warmer than a plain shell.
The Winter Voyager
The Winter Voyager is a cold-weather coat and jacket family, and stockists such as Harry Rosen list Winter Voyager coats in baby cashmere with Green Storm System.
It combines the warmth of cashmere with the brand’s wind and rain treatment, which makes it a practical winter coat for cold, damp days.
The Icer Jacket
Loro Piana describes its Icer jacket as made of cashmere with a Storm System water-repellent, wind-resistant finish, lined in checked cotton, with a hood concealed in the collar.
The brand presents it for both mountain and town wear.
Its product page also advises not wearing it two days in a row, so the fibres can recover their natural structure.
The Sebring Coat
The Sebring is a knee-length raincoat.
Harry Rosen lists a Sebring technical coat with a polyester outer, a polyurethane membrane, a cashmere lining, suede trim and Green Storm System, marked dry clean only.
A knee-length coat covers more of a tailored suit than a jacket, which makes it a useful choice over business clothes in the rain.
How to Wear Loro Piana in the Rain
Check the label of each garment for Rain System, Storm System or Green Storm System before you wear it in wet weather.
Put a treated outer layer over untreated knitwear, shirts and trousers, so the rain meets the treated cloth first.
Choose a coat long enough to cover your jacket and the top of your trousers if you will be walking in steady rain.
Carry an umbrella for long walks, and keep leather bags and suede shoes for dry days.
Wear (city commute): a Storm System field jacket over a navy merino crew-neck, grey wool trousers and dark brown leather Chelsea boots with rubber soles.
Wear (business): a knee-length technical raincoat over a navy suit, a white shirt and black leather Derby shoes with rubber soles.
Wear (weekend): a hooded cashmere jacket with a weather finish over a cream roll-neck, dark jeans and brown waxed leather boots.
Loro Piana Clothes That Need Protecting From Rain
Most Loro Piana knitwear, shirts, silk and leather goods are not made for rain, so protect them with an outer layer or an umbrella.
Cashmere and wool knitwear
Rain soaks into a jumper quickly, and wet knitwear stretches under its own weight.
Wear a water-resistant outer layer over cashmere and wool knits on wet days.
If a jumper gets wet, press out the water gently, lay it flat on a towel to dry away from radiators and direct sunlight, and reshape it while damp.
Woven wool and cashmere coats and jackets
Woven wool jackets and coats can be hung to dry on a broad, shaped hanger, which keeps the shoulders in shape.
Dry them at room temperature, away from radiators, which can discolour or damage wool, and brush them gently once they are dry.
Silk
Water can mark silk, so keep silk ties, scarves and shirts out of the rain where you can.
If silk gets wet, blot it with a clean, dry cloth rather than rubbing it, let it dry away from direct heat, and take any marks to a specialist cleaner.
Leather and suede
Rain can dry out leather as it evaporates, so wipe off standing water as soon as you can.
Let leather dry naturally at room temperature rather than with a hairdryer or on a radiator, and apply a leather conditioner once it is nearly dry.
Brush suede once it is dry to lift the nap, and use a protective spray made for suede before you wear it in uncertain weather.
Caring for Weather-Treated Garments
Follow the care label of each garment, because Loro Piana’s treatments are applied to many different fabrics.
Loro Piana’s product pages recommend professional cleaning, particularly for garments with delicate details, and some of its raincoats are sold as dry clean only.
Let a wet garment dry at room temperature before you put it away, and keep it away from radiators, hairdryers and direct sunlight.
Store outerwear in a dry place, away from heat and light, with moth repellent if it contains wool or cashmere.
Ask a specialist cleaner before you use any home reproofing spray on a branded finish.
So, Can You Wear Loro Piana in the Rain?
Yes, if you choose garments made for it: outerwear with Rain System, Storm System or Green Storm System will cope with showers and a wet commute.
Knitwear, silk and leather need protecting from rain, and any wet garment needs to dry slowly, away from heat.
