Waterproof and breathable fabrics use membranes with small pores that block water droplets while still allowing sweat vapor to pass through, such as those used by GORE-TEX; other brands also utilize this technology.

For optimal waterproof breathable fabrics with a rating of 20,000 millimeters or higher that provide both waterproofing and breathability, such fabrics are ideally suited to people who spend many days outside in heavy rain or snowfall.

1. Gore-Tex

GORE-TEX waterproof membrane provides breathable weather protection. Featuring microscopic pores 20,000 times smaller than a drop of water and 700 times larger than sweat molecules, GORE-TEX allows moisture vapor from inside your jacket to escape while keeping rain and snow at bay.

Gore-TEX fabric is highly resilient and repairable, making it a fantastic choice for outdoor clothing. However, in order to preserve its long-term use and keep its durability intact it is vital that its care be properly observed.

Gore-Tex fabrics come in three varieties, which differ based on how their outer and inner layers are constructed. 2L construction is most prevalent and straightforward while 3L bonds the lining to membrane for enhanced durability.

2. eVent

As you move outside, your body generates heat and moisture that must escape; otherwise, your body could overheat and feel damp and uncomfortable. A rain jacket that won’t allow this moisture to escape can leave you clammy and sweaty.

GORE-TEX and eVent membrane fabrics offer comfort in both wet and dry conditions by allowing sweat vapor to escape, thus relieving that uncomfortable clammy feeling. While more expensive than cheaper PU-coated options, they last longer and perform more effectively.

Air-permeable fabrics such as eVent and Polartec’s NeoShell have received high marks from outdoor publications, and are certified under OEKO-TEX Standard 100 certification, making them popular choices among brands like Flylow, Marmot and Strafe who utilize them in their apparel lines.

3. Pertex

Pertex’s expertise as parachute canopy fabric manufacturers has allowed it to develop lightweight performance fabrics such as Pertex Shield AP and the newer Pertex Shield+ waterproof/breathable fabrics, used by brands like The North Face, Patagonia, Rab and Montane in hardshell jackets.

All hardshell fabrics should provide shelter against snow, rain and wind while remaining breathable. Pertex Shield fabrics offer the ideal balance of wind resistance and breathability with airflow that transports sweat away from your body efficiently.

Pertex Shield fabrics are designed for intensive mountain pursuits where weight is an issue and comfort is of utmost importance. Available in 2.5 and 3-layer constructions with lightweight face fabrics that feature waterproof, windproof, and breathable membranes – Pertex Shield fabrics allow you to move swiftly while remaining comfortable.

4. Patagonia

Patagonia pioneered eco-friendly gear long before it became fashionable, which explains their ability to charge premium rates for their products while building customer loyalty with them.

Yvon Chouinard founded Patagonia with the belief that people come before profits, and has upheld this credo throughout its history. Examples of this commitment to employee wellbeing at Patagonia are its “Let My People Go Surfing Policy” and rotating work schedules.

In 2017 and since 2012, this company has also been active politically; filing suit against the federal government over proclamations changes that reduce Grand Staircase-Escalante and Bears Ears National Monuments. They use renewable energy sources such as wind or solar to power their facilities.

5. Marmot

Marmot jackets and rain coats provide reliable warmth and waterproof protection, perfect for outdoor adventures of all kinds. Their top-of-the-line materials ensure years of fun outdoor adventures!

Marmot’s PreCip Rain Shell is a fan favorite, featuring PFC-free NanoPro recycled nylon face fabric and its trademark dry touch finish. Additionally, its helmet-compatible hood, adjustable cuffs and pit zips enable heat release as you exert yourself during exercise.

This jacket utilizes Down Defender treatment, which helps safeguard down insulation against moisture damage and maximize performance under damp conditions. Furthermore, ExpeDRY insulation helps your body wick away excess moisture to help you remain warm and dry throughout the day.

6. Pertex Shield+

Pertex Shield+ fabrics provide waterproof protection from snow, rain and wind while being breathable enough to release sweat vapour generated during physical exertion. Incorporating good garment design is key for maintaining optimal results; Pertex Shield+ fabrics offer just such solutions.

Pertex’s Microporous Shield Pro fabrics are specifically engineered for extended use in harsh conditions, featuring numerous evenly spaced pores to minimise moisture build-up. You’ll find them used by top outdoor gear manufacturers like Arc’teryx and Patagonia.

Pertex Shield+ fabric layers (upper, membrane and support material) are composed from one material for easy recycling at the end of product life cycles. Martini Sportswear utilizes Shield+ Revolve in their weatherproof jackets and salopettes.
