In recent years, softshell jackets have gained popularity among outdoor enthusiasts and in the workwear industry due to their comfort, flexibility, windproof properties, and water repellency. Compared to hardshell jackets, softshells excel in breathability and freedom of movement, but their waterproof capabilities often raise concerns. This article explores the waterproof properties of softshell jackets, discussing their materials, construction, use cases, and providing real-world examples to help readers better understand when and how a softshell jacket performs best in terms of water resistance.

 

1. Materials and Water Resistance of Softshell Jackets

One of the defining features of a softshell jacket is its water repellency, rather than full waterproofing. Most softshell fabrics are made from synthetic fibers like polyester or nylon, with the outer layer treated with DWR (Durable Water Repellent). This treatment allows water to bead up and roll off the surface, effectively protecting against light rain or snow for short periods. However, softshell fabrics do not have the fully waterproof membrane structure found in hardshells like GORE-TEX, meaning they cannot withstand prolonged exposure to heavy rain or submersion in water.
The key difference between water repellency and waterproofing is that the former is designed to block light moisture for a short time, whereas the latter is meant to prevent any water penetration even during extended rain or wet conditions. Softshell jackets, therefore, offer basic protection but are not suitable for extreme wet environments.

 

2. The Balance Between Waterproofing and Breathability

Another core feature of softshell jackets is their superior breathability. Compared to hardshells, softshells allow moisture from perspiration to escape more easily during high-intensity activities, preventing discomfort from sweat buildup. This breathability comes from the fabric's looser weave, which simultaneously limits the jacket's waterproof capabilities.
Waterproof materials are often less breathable due to their airtight structure. In contrast, softshells trade off some of their water resistance for increased breathability, making them ideal for activities that involve continuous movement and sweating. For example, during hiking or mountain climbing, softshells help keep the wearer dry by releasing excess moisture from inside, reducing the risk of feeling cold due to trapped sweat.

 

3. Factors Affecting the Water Resistance of Softshell Jackets

Durability of the DWR Treatment
The DWR treatment is the key to a softshell’s water-repellent function, but its effectiveness is not permanent. Over time, and with regular use and washing, the DWR coating wears off, reducing the fabric's ability to repel water. When this happens, water can seep into the fabric more easily. To maintain water resistance, users should periodically reapply a DWR spray to restore the jacket’s water-repellent properties.

Seams and Design Structure
Aside from the fabric, the design and construction of seams, zippers, and other features also impact water resistance. Many softshell jackets lack fully taped seams, meaning water can potentially enter through the stitching. Additionally, unsealed zippers can act as points of entry for water. In heavy rain conditions, these areas become vulnerabilities where water can infiltrate the jacket.

Fabric Thickness and Layering
Softshell jackets vary in fabric thickness and the number of layers. Multi-layer softshells with a fleece lining may offer better warmth and insulation, but these features do not necessarily enhance waterproofing. While thicker softshells might provide slightly more resistance to moisture, they still cannot match the impermeability of waterproof hardshells. Therefore, it is important to select a jacket based on its intended use and not solely on its layering.

 

4. Use Cases and Water Resistance

Softshell jackets are ideal for specific environments and use cases, particularly where the weather is mild and rain exposure is light or temporary. Here are some typical scenarios where the water resistance of a softshell jacket is sufficient:

Light Rain Conditions
Softshell jackets are perfect for short trips in light rain. In activities like hiking or cycling, where rain may occur intermittently, softshell jackets' water-repellent surface effectively keeps the wearer dry while maintaining breathability. Even in brief showers lasting up to an hour, softshells can prevent moisture from seeping in, ensuring the wearer stays comfortable.

Windy and Snowy Weather
Softshell jackets also perform well in windy and snowy conditions. Their windproof properties block cold gusts, and the DWR treatment ensures that snowflakes roll off before melting. However, in wet snow or prolonged exposure to snowfall, the jacket’s water resistance will start to weaken. In such situations, a waterproof hardshell or layering system may be required.

Everyday Commuting
For daily use in urban settings, softshell jackets offer sufficient protection during cold, dry days or brief light rain. In regions with colder but less rainy climates, the softshell provides the necessary insulation and windproofing for comfortable wear. Although not suited for heavy rain, softshells work well for the typical challenges of urban commuting.

 

5. Case Studies

Case Study 1: Moderate Hiking Activity
During a 10 km spring hike, participants were faced with cloudy weather. Initially, they chose to wear softshell jackets due to the moderate temperatures and stable conditions. Halfway through the hike, it started drizzling, which lasted for about an hour. The softshell jackets performed well under the light rain, keeping the hikers dry and comfortable while allowing sweat to escape. However, as the rain intensified, the jackets began to soak through, and the hikers had to switch to hardshell jackets to prevent getting fully wet.

Case Study 2: Urban Winter Commute
In an urban setting, a commuter facing a cold, snowy winter day opted for a softshell jacket. The windproof qualities kept them warm while biking to work, and the light snow was effectively repelled by the DWR treatment. However, had the snowfall turned into rain or become heavier, the softshell would have been less effective, potentially allowing moisture to penetrate after a prolonged commute.

 

6. Limitations of Softshell Jacket Waterproofing

Despite their advantages, softshell jackets have clear limitations when it comes to waterproofing. In prolonged exposure to heavy rain, the DWR coating will no longer provide adequate protection, and water will eventually penetrate the fabric. Additionally, seams and zippers, which are typically not waterproofed, can allow moisture to enter the jacket. Therefore, for individuals expecting to spend extended time in wet environments, a softshell may not be the best choice. Fully waterproof hardshell jackets or garments designed with a waterproof membrane will provide better protection in these scenarios.

 

 

Softshell jackets offer an excellent balance of breathability, windproofing, and water repellency, making them a popular choice for outdoor activities in mild or variable weather. However, they are not fully waterproof and should not be relied on in heavy rain or prolonged wet conditions. When choosing a softshell jacket, it is important to consider the specific use case and the likely environmental conditions. For high-intensity activities where moisture management is key, a softshell jacket excels;
