Loro Piana Rain System vs. Storm System: What's the difference?

The core difference between Loro Piana's Rain System and Storm System technologies comes down to the level of weather protection they offer. The Rain System is an ultralight, breathable treatment designed for moderate rain, making it perfect for everyday wear without added bulk. The Storm System, on the other hand, is a more robust, laminated technology providing superior waterproofing and windproofing for harsher conditions like heavy downpours and strong winds.

Here's everything you need to know to choose the right fabric technology for your needs.

Loro Piana Rain System

The Rain System is Loro Piana's solution for creating supremely elegant, water-resistant outerwear that feels light and comfortable. By applying a proprietary hydrophobic treatment to their luxurious fabrics like wool and cashmere, the Rain System makes water droplets bead up and roll off the surface while maintaining the material's natural softness and breathability. It's designed to offer protection from the elements without the stiffness or weight of traditional rain gear.

• What it is: A lightweight, breathable fabric treatment that provides high water resistance for fine textiles like wool and cashmere.
• Key features: Hydrophobic finish that repels water, exceptional breathability, maintains the natural feel and softness of the fabric, quick-drying.
• Price: Jackets and coats typically range from $3,000 to $4,500.
• Materials/Construction: Applied to Loro Piana’s signature fabrics, including fine wools, cashmere, and technical blends, without altering their luxurious texture.
• Pros: Incredibly lightweight and comfortable for everyday use, highly breathable to prevent overheating, offers a discreet look without a technical appearance, versatile enough for most urban weather.
• Cons: Provides water resistance, not full waterproofing, so it's less suitable for prolonged heavy downpours, offers minimal wind protection compared to Storm System.

This is the ideal choice for those who need functional, stylish outerwear for city life in climates with mild to moderate rainfall.

Loro Piana Storm System

The Storm System is Loro Piana's answer to severe weather, offering complete waterproofing and windproofing in one sophisticated package. This two-part technology combines the Rain System's water-repellent finish on the outer fabric with an ultra-thin, breathable membrane that is bonded to the inner side. This barrier stops wind and water from penetrating while allowing moisture to escape, ensuring you stay dry and comfortable in challenging conditions without sacrificing Loro Piana's classic elegance.

• What it is: An advanced, dual-layer technology that makes natural fabrics completely waterproof and windproof while retaining breathability.
• Key features: Laminated waterproof and windproof membrane, durable water-repellent outer treatment, often features sealed seams for maximum protection.
• Price: Pieces generally fall between $4,000 and $6,000.
• Materials/Construction: Laminated to premium wool, cashmere, and other fine fabrics, creating a high-performance textile that still feels luxurious.
• Pros: Superior protection against heavy rain, wind, and even snow, remarkably durable for long-term wear, provides warmth by blocking wind chill, a truly all-weather solution.
• Cons: Heavier and slightly stiffer than Rain System fabrics due to the membrane, less breathable during high-exertion activities, higher price point.

It's built for individuals who require uncompromising weather protection in unpredictable or harsh climates without giving up a refined aesthetic.

Loro Piana Rain System vs. Storm System Comparison

Weather Protection & Performance

This is the most critical distinction between the two. The Rain System is designed to be highly water-resistant. It excels in light to moderate showers, causing water to bead and roll off. However, in a full-blown downpour or during prolonged exposure to rain, moisture may eventually seep through. It offers minimal protection from wind.

The Storm System is fully waterproof and windproof. Its laminated membrane acts as an impenetrable barrier against both heavy rain and strong gusts of wind. This makes it a far superior choice for serious weather, keeping you completely dry and negating the effects of wind chill.

Feel & Breathability

The Rain System has almost no impact on the hand-feel of the fabric. A cashmere coat with Rain System still feels like a soft, luxurious cashmere coat. Its primary advantage is very high breathability, allowing moisture vapor to escape easily, making it comfortable for all-day wear and commuting.

Because the Storm System involves bonding a membrane to the fabric, it yields a garment with slightly more structure and a bit less drape. While still impressively soft for a technical fabric, it doesn't have the same feather-light feel as a Rain System-treated piece. It is breathable, but the membrane makes it less so than the open structure of the Rain System fabric.

Price & Value

Outerwear featuring the Rain System generally starts around $3,000, while Storm System pieces are a step up, often starting at $4,000 and going higher. The price difference directly correlates with the level of technology and protection offered.

For someone living in a city with moderate weather, the Rain System provides excellent value, adding crucial functionality to a luxury garment. For those in climates known for wind and heavy rain, the extra investment for the Storm System is justified, as it provides true four-season protection and durability that make it a reliable cornerstone of a wardrobe.

Which One Should You Choose?

Both are outstanding technologies, but they serve distinctly different needs and climates.

Choose the Rain System if:

• You live in an urban environment with mild to moderate rainfall.
• You prioritize a lightweight feel and maximum breathability.
• Your main requirement is keeping a luxury coat protected during unexpected showers.
• You want a water-resistant layer that feels virtually identical to an untreated fabric.

Choose the Storm System if:

• You regularly face heavy rain, strong winds, or even snow.
• Your top priority is complete waterproofing and wind protection.
• You don't mind a slightly more substantial garment in exchange for superior weatherproofing.
• You need a versatile travel piece that can handle variable and harsh weather conditions.

Frequently Asked Questions

What’s the main difference between Rain System and Storm System?

The main difference is protection level. Rain System is a water-resistant treatment ideal for moderate rain, focusing on lightness and breathability. Storm System is a fully waterproof and windproof membrane for protection against heavy rain and high winds.

Is the Storm System completely waterproof?

Yes. The Storm System uses a technical membrane and is often paired with sealed seams on select styles to provide true waterproof protection against steady, heavy rain.

Is the Rain System just for light drizzle?

The Rain System is effective in more than just a light drizzle. It can comfortably handle moderate or intermittent rain showers, making it perfect for daily commuting and city life. It is not designed for prolonged torrential downpours.

Why are Loro Piana jackets so expensive?

The cost reflects the quality of the raw materials (like Grade-A cashmere and superfine wools), the advanced, proprietary fabric technology, the meticulous Italian craftsmanship, and the brand's position as a top-tier luxury house.

How do you care for a Loro Piana jacket with these systems?

Always refer to the specific care label on the garment. However, for outerwear of this caliber, professional green dry cleaning is typically recommended to preserve the integrity of both the luxury fabric and the technical treatment.

Which system is more versatile?

For general daily wear in most major cities, the Rain System could be considered more versatile, as its lightness and breathability make it comfortable in a wider range of non-severe conditions. For travel or for someone living in a climate with truly variable weather (like London or a coastal region), the Storm System's all-around protection makes it more functionally versatile.

Does the Storm System feel bulky or heavy?

While it is heavier and more structured than a piece treated with the Rain System, Loro Piana engineers its Storm System garments to be as light and comfortable as possible. They do not feel bulky or cumbersome compared to typical high-performance outerwear.

Which one offers better value?

Value depends entirely on your needs. If you don't face harsh weather, the Rain System offers tremendous value by adding useful functionality. If you do need serious protection, the Storm System provides the security that a regular coat can't, making it a worthwhile investment to protect you from the elements.
