This guide covers everything you should know about waterproof jackets, helping you select the right one, maintain its performance, and make the most out of it in various weather conditions.

What is a Waterproof Jacket?

A waterproof jacket is a type of outerwear specifically designed to keep you dry in wet conditions, making it an essential piece of gear for anyone who spends time outdoors. These jackets are crafted from waterproof materials, such as membranes or coatings, that prevent water from penetrating the fabric. Whether you’re hiking, hunting, skiing, or simply navigating a rainy day in the city, a waterproof jacket offers maximum protection from the elements.

The key to a good waterproof jacket lies in its ability to balance waterproofing with breathability. This means that while the jacket keeps rain and snow out, it also allows moisture from sweat to escape, preventing overheating and discomfort. Features like adjustable cuffs, hems, and hoods enhance the jacket’s ability to seal out water, ensuring a snug fit that keeps you dry.

When selecting a waterproof jacket, it’s crucial to consider factors such as waterproof ratings, breathability, and durability. A higher waterproof rating indicates a more robust barrier against water, while breathability ratings measure how well the jacket allows moisture to escape. By choosing a jacket with the right combination of these features, you can ensure it meets your specific needs and activities.

What Makes a Jacket Waterproof?

A waterproof jacket is designed to prevent water from penetrating the fabric, keeping the wearer dry in wet conditions. This is achieved through special materials, waterproof coatings or membranes, and seam-sealing techniques. Waterproof jackets come in various levels of water resistance, depending on the technology used and the intended use of the jacket. Generally, a waterproof jacket is made up of the following components:

• Waterproof Membrane or Coating Waterproof jackets often use a membrane or coating to keep water out. This layer is usually made from a material that blocks water while allowing moisture (sweat) to escape, providing breathability. Membranes are typically more durable and breathable than coatings, making them ideal for active outdoor activities.

• Durable Water Repellent (DWR) Finish The outer layer of a waterproof jacket is often treated with a DWR finish, which causes water to bead up and roll off the fabric. This treatment prevents water from saturating the outer fabric, enhancing the jacket’s ability to keep moisture out. DWR finishes may wear off over time and require reapplication to maintain effectiveness.

• Seam Sealing Seam sealing is an essential feature for waterproof jackets, as stitching can create tiny holes where water can seep through. Seam-sealed jackets have tape or other materials applied along the seams to prevent leaks, providing complete waterproof protection.

Waterproof zips are another crucial feature that enhances the jacket's waterproof functionality. These zips, along with taped seams, ensure that no water can penetrate through the openings, contributing to the overall durability and effectiveness of the jacket.

Types of Waterproof Jackets

Waterproof jackets come in various types, each suited for different activities and levels of exposure to the elements. Understanding the different types can help you choose the jacket that best fits your needs.

Hardshell Jackets Hardshell jackets are highly durable and designed for maximum weather protection. They feature waterproof membranes and often include full seam sealing and reinforced fabrics. These jackets are commonly used for extreme weather conditions and high-intensity activities like mountaineering or backcountry skiing. Hardshells are generally less breathable than softshell jackets but offer the best protection against wind, rain, and snow.

Softshell Jackets Softshell jackets are designed for breathability and flexibility, making them ideal for high-energy activities like hiking or cycling in light rain or snow. They typically provide some level of water resistance rather than full waterproofing, with a DWR finish that repels light rain. Softshells prioritize comfort and range of motion but are less effective in heavy rain. As a type of water resistant jacket, they are suitable for light showers but not heavy downpours.

Rain Jackets Rain jackets are lightweight, packable options designed for everyday use or short outdoor activities in wet weather. They offer waterproofing but may not be as durable as hardshells. Rain jackets are excellent for casual wear, urban environments, or outdoor activities where a lighter jacket is preferred. Many rain jackets are easy to store in a backpack, making them convenient for unexpected rain.

Insulated Waterproof Jackets Insulated waterproof jackets combine waterproofing with added insulation, providing both warmth and protection from rain. These jackets are ideal for cold, wet environments, such as winter hiking or skiing. Insulated waterproof jackets can be heavier than other options but provide all-in-one protection against cold and moisture.

Waterproof Materials and Construction

The effectiveness of a waterproof jacket largely depends on the materials and construction techniques used. The most common waterproof materials include membranes, coatings, and laminates, each offering unique benefits:

• Membranes: These are thin, porous layers that block water from entering while allowing moisture to escape. 

• Coatings: Applied as thin layers on the fabric, coatings like DWR (durable water repellent) and PU (polyurethane) create a barrier that prevents water penetration. While effective, coatings may require reapplication over time to maintain their performance.

• Laminates: These involve bonding multiple layers of fabric with a waterproof membrane or coating in between, providing enhanced protection and durability.

Waterproof jackets can be constructed in several ways, each offering different levels of protection and comfort:

• 2-layer construction: This involves bonding an outer fabric to a waterproof membrane, providing a balance of protection and flexibility.

• 2.5-layer construction: Here, an outer fabric is bonded to a waterproof membrane, with a thin coating or print applied to the inner layer. This construction is lightweight and packable, making it ideal for activities where weight and space are concerns.

• 3-layer construction: This method sandwiches a waterproof membrane between an outer and inner fabric, offering maximum protection and durability, suitable for extreme conditions.

Fully taped seams are a critical feature in waterproof jackets, as they prevent water from seeping through the stitching. Look for jackets with fully taped seams or critically taped seams to ensure maximum protection against leaks.

When choosing a waterproof jacket, consider the type of material and construction that best suits your needs. Higher-quality materials and construction methods will provide better protection and durability, ensuring your jacket performs well in various weather conditions.

Understanding Waterproof Ratings

Waterproof ratings measure the level of water resistance a jacket offers, usually indicated in millimeters (mm). This rating represents the amount of water the fabric can withstand before leaking. The higher the rating, the more waterproof the jacket. Common waterproof ratings include:

• 5,000 mm – Suitable for light rain or drizzle; provides basic waterproofing.

• 10,000 mm – Offers moderate waterproofing, ideal for light to moderate rain.

• 15,000 mm – Effective for heavy rain; suitable for prolonged exposure to wet conditions.

• 20,000 mm and above – Provides high waterproofing, ideal for extreme weather and long-duration exposure to heavy rain or snow.

In addition to waterproof ratings, breathability ratings indicate how well a jacket allows sweat to escape, often measured in grams per square meter (g/m²). Higher breathability ratings (20,000 g/m² or above) are better for high-intensity activities, as they help keep you comfortable and dry from the inside out.

A waterproof jacket buying guide can help consumers make informed decisions based on waterproof ratings, breathability, and other essential factors.

Key Features to Look for in Waterproof Jackets

When choosing a waterproof jacket, consider the features that will best meet your needs and enhance performance in various conditions.

• Adjustable Hood An adjustable hood allows for a snug fit around the face, providing better protection from wind and rain. Some hoods are helmet-compatible, which is essential for mountaineers or cyclists.

• Ventilation Zippers Ventilation zippers, or pit zips, allow you to release heat and moisture, improving breathability during intense activity. They’re particularly helpful for high-intensity activities where sweat buildup can cause discomfort.

• Adjustable Cuffs and Hem Adjustable cuffs and hems help seal out wind and water, keeping you dry and comfortable. Elastic or Velcro cuffs provide a custom fit around the wrists, while adjustable hems prevent water from entering at the waist.

• Pockets with Waterproof Zippers Waterproof pockets keep your essentials dry in wet conditions. Look for pockets with waterproof zippers or storm flaps to prevent water from entering and damaging electronics or other items.
