At just 13.3oz, this jacket feels light on your back. You can pack it easily for any day hike or weekend trip.
Is this jacket the right pick for your next adventure? Let’s explore its features, comfort level, and real world performance in detail below.
In a Nutshell
Here’s a quick summary of what makes this jacket stand out:
-
Eco-friendly build: The face fabric uses 100% recycled materials, with over 50% total recycled content. It’s also PFAS-free, so you get performance without harsh chemicals.
-
Strong weather protection: With a 20,000mm waterproof rating and 20,000g/m²/24hrs breathability, this jacket handles wet conditions while letting sweat escape.
-
Smooth zipper system: The 13-inch pit zips use YKK sliders with fabric flaps. They glide easily and add extra ventilation when you need it.
-
Comfortable fit: The regular cut feels soft against your skin. It moves with you instead of feeling stiff or bulky.
-
Some tradeoffs exist: The 2.5-layer fabric is thin, so it needs gentle care. Condensation can build up faster than in heavier jackets.
-
Great for day trips: This jacket packs down small and works well for shorter hikes. It may not match premium options for extended, heavy duty use.
Material and Fabric Quality
The Rab Downpour Eco Jacket uses Pertex Shield Revolve, a 2.5-layer fabric built for performance and sustainability. This material combines a recycled face fabric with smart engineering to keep you dry without unnecessary bulk.
What makes this fabric special? The face layer is 100% recycled material. The overall jacket contains more than 50% recycled content throughout. This means Rab prioritizes environmental responsibility without cutting corners on function.
The waterproof rating reaches 20,000mm hydrostatic head. This number tells you how much water pressure the fabric can handle before leaking. For most outdoor activities like day hiking and light backpacking, this level of protection works well. You stay dry in moderate to heavy rain.
Breathability matters just as much as waterproofing. The Downpour Eco breathes at 20,000g/m²/24hrs MVTR. This measurement shows how much moisture vapor escapes through the fabric over time. The balance between these two specs is solid, keeping sweat from building up inside while rain stays out.
One important detail: the fabric is PFAS-free. Traditional waterproof coatings use fluorocarbons that persist in the environment. This jacket avoids those chemicals entirely, making it a cleaner choice for nature lovers.
The 2.5-layer construction does come with trade-offs. Thinner fabrics mean lighter weight, which is great for packability. However, thinner materials require more careful handling during use and storage. Rough treatment can damage the coating over time.
Compared to premium alternatives with Gore-Tex or similar membranes, this fabric offers good performance at a different engineering level. The Pertex Shield Revolve prioritizes weight and packability over maximum condensation management. This makes it ideal for active users who value mobility.
The fabric feels soft and comfortable against your skin. Many users appreciate the smooth, quiet material that doesn’t create rustling noise. The face fabric drapes naturally, giving the jacket a streamlined appearance that works for outdoor adventures or casual wear.

Waterproofing and Breathability Performance
The Rab Downpour Eco Jacket strikes a solid balance between keeping you dry and letting moisture escape. The 20,000mm waterproof rating means heavy rain won’t soak through, even during sustained downpours on longer hikes.
Breathability performs equally well at 20,000g/m²/24hrs MVTR. This metric tells you how much sweat vapor the fabric releases per square meter in a day. In simple terms, your sweat doesn’t trap inside the jacket as you move uphill or work hard.
Here’s the real story: the 2.5-layer Pertex Shield Revolve fabric does its job without the thickness of premium alternatives. You get genuine waterproofing without feeling like you’re wearing a plastic bag. The soft feel against your skin comes from that recycled face fabric, which also happens to be PFAS-free.
One honest limitation exists. Condensation management stays modest compared to Gore-Tex jackets or thicker membranes. On cold, humid days when you’re moving slowly, moisture can build up inside faster than the breathability rating suggests. This isn’t a dealbreaker for day hikes, but it matters for all-day expeditions in wet conditions.
The pit zips help manage this issue. Those 13-inch vents let you dump heat and moisture quickly without removing the jacket entirely. Open them during climbs, close them when the wind picks up.
The thin construction also means you need to treat the fabric with care. Rough handling or sharp gear rubbing against it can damage the membrane. This isn’t unusual for lightweight jackets, but it’s worth knowing.
For most hikers tackling variable weather on shorter trips, this performance level feels right. The waterproofing keeps rain out reliably, and the breathability stays responsive to your activity level. You won’t feel trapped by sweat buildup during moderate exertion. The trade-off comes when conditions get extreme or your trip stretches into a full day of constant rain and effort.
Fit, Comfort, and Wearability
The Rab Downpour Eco Jacket delivers a streamlined fit that works well for active outdoor use. The regular cut sits close to your body without feeling restrictive, making it ideal for hiking and movement. The back length measures 29.5 inches in a medium size, which provides solid coverage without excess fabric dragging down.
Comfort stands out as a key strength here. The Pertex Shield Revolve fabric feels soft against your skin, not stiff or plasticky like some rain jackets. You won’t feel like you’re wearing a plastic bag. The material moves with you naturally, and the lightweight construction at 377 grams means you barely notice it’s there.
The 13 inch pit zips make a real difference during active use. You can open them quickly to release heat buildup when you’re moving fast or the weather warms up. The YKK sliders glide smoothly, and fabric flaps protect the zipper teeth from snagging. This feature helps manage moisture that builds up inside without removing the entire jacket.
Packability is exceptional for this category. The jacket compresses down to a small bundle that fits easily into a backpack pocket or day pack. This makes it perfect for hikers who want protection without carrying bulk. You can grab it for unpredictable weather without weighing yourself down.
One important consideration: the 2.5 layer fabric is thinner than premium alternatives. This means you should avoid rough terrain contact or sharp branches that could snag the material. The construction trades ultimate durability for lightweight performance and packability. For day hikes and variable weather conditions, this tradeoff makes sense.
The fit accommodates different body types reasonably well. The regular cut works for most standard builds without excessive baggy areas. If you prefer a looser fit or plan to layer heavily underneath, you might size up. The streamlined design means minimal excess material at the torso and sleeves, which helps reduce water pooling during heavy rain.
Overall, wearability feels balanced. You get comfort, reasonable protection, and minimal weight without sacrificing functionality.

Sustainability and Environmental Impact
Rab’s commitment to sustainability runs deep with the Downpour Eco Jacket. The 100% recycled face fabric represents a meaningful step toward reducing waste in outdoor gear production. This choice matters because it keeps plastic out of landfills and gives new life to existing materials.
The jacket goes further by achieving over 50% total recycled content across all components. This includes the lining and other structural parts, not just the outer shell. When you wear this jacket, you’re supporting a production method that uses fewer virgin resources.
One standout feature deserves special attention: the fabric is PFAS-free. These fluorocarbon chemicals (also called “forever chemicals”) persist in the environment for decades. Rab removed them entirely, which means the jacket won’t release harmful compounds during its lifetime or after disposal. This decision reflects growing awareness about chemical pollution in outdoor gear.
The Pertex Shield Revolve fabric itself embodies efficiency. A 2.5-layer construction uses less material than thicker alternatives while still delivering solid performance. Less fabric means lower environmental impact during manufacturing, from energy use to water consumption.
Durability plays a role in sustainability too. The thin construction demands careful handling, but when treated properly, this jacket lasts for years. Gear that survives multiple seasons reduces the need for frequent replacements, which ultimately lessens environmental impact.
The jacket’s exceptional packability connects to sustainability as well. A smaller packed size means lighter backpacks and less energy spent during transport. This might seem minor, but it adds up across thousands of users.
Rab’s approach avoids greenwashing. They don’t claim perfection or use vague sustainability language. Instead, they focus on concrete choices: recycled materials, PFAS elimination, and efficient construction. The Downpour Eco Jacket proves that outdoor gear can protect the environment without sacrificing performance.
For hikers who care about their environmental footprint, this jacket offers real substance. It balances active weather protection with genuine sustainability credentials that extend beyond marketing claims.
Weight, Packability, and Portability
The Rab Downpour Eco Jacket weighs just 13.3 ounces in size medium, making it genuinely light for a waterproof shell. This weight sits between ultralight options and heavier premium jackets, hitting a practical sweet spot for most hikers.
Packability stands out as a real strength here. The jacket compresses into a remarkably small bundle that fits easily into your backpack’s side pocket or main compartment. You won’t feel like you’re carrying extra gear. The streamlined design and lightweight construction make this possible. Many hikers appreciate this feature for variable weather days when you’re unsure if rain will hit.
The 13 inch pit zips contribute to packability in an unexpected way. When you’re active and warm, you can open them for ventilation instead of stuffing the jacket away entirely. This flexibility means you carry it less often. The YKK sliders work smoothly and include a protective fabric flap to prevent accidental openings.
Portability matters during movement, and here the Rab performs well. The regular fit doesn’t bunch up or create excess fabric when you fold it. The back length of 29.5 inches in medium keeps the jacket proportional without awkward draping. The soft Pertex Shield Revolve fabric packs down without permanent creasing, so it springs back to shape quickly.
One consideration exists: the 2.5 layer fabric is thinner than premium alternatives. This means you should pack it carefully to avoid snags or punctures during transport. Store it in a dedicated pocket rather than loose in your pack with sharp objects.
The weight and packability combination makes this jacket ideal for day hikes and weekend trips. You get genuine waterproof protection without the burden of heavier shells. The balance between protection and portability feels right for active outdoor use. Ultralight enthusiasts might seek even lighter options, while weekend warriors will find this weight entirely manageable. The jacket earns its reputation as a practical companion for unpredictable weather.

Day hikers benefit most from this design. The 13.3 ounce weight means you barely notice it on your shoulders. You can leave it in your backpack all day without regret, then pull it on when clouds roll in.
Weekend adventurers find real value here too. The jacket compresses into a tiny bundle that fits anywhere. Your other gear stays protected while you move through changing conditions without feeling weighed down.
Environmental-conscious outdoor lovers should pay attention. The PFAS-free construction means you get waterproofing without harmful chemicals touching your skin. The 100% recycled face fabric and over 50% total recycled content appeal to people who care about their impact on nature.
Active hikers during moderate rain will appreciate the pit zips. You dump heat quickly without removing the entire jacket. The 20,000mm waterproofing handles steady rain and light downpours effectively. The 20,000g breathability rating keeps moisture from building up inside during movement.
Fair weather hikers should consider this option carefully. The 2.5 layer fabric is thinner than premium alternatives. You need to handle it gently to avoid snags and tears. If you regularly push through heavy brush or expect rough conditions, a tougher jacket might serve you better.
Ultralight backpackers appreciate the minimal weight and packability. You get genuine waterproofing without carrying excess material. The streamlined fit means no baggy fabric flapping around.
Comfort seekers benefit from the soft Pertex Shield Revolve material. It feels pleasant against your skin, not stiff or scratchy like cheaper rain jackets. The regular fit accommodates layers without feeling restrictive.
Skip this jacket if you need maximum condensation management. Premium Gore-Tex alternatives handle internal moisture better during intense activity. If you prioritize durability over weight, look elsewhere.
The Rab Downpour Eco Jacket targets people who want lightweight protection with genuine sustainability credentials. You get reliable waterproofing and breathability in a package that respects both your comfort and the environment.
Final Verdict
The Rab Downpour Eco Jacket earns its place as a smart choice for many hikers. It blends sustainability with real performance. This combination is hard to find in other rain shells.
Compared to the Lightheart Gear Rain Jacket, the Rab offers better breathability numbers. The Frogg Toggs Xtreme Lite feels flimsier in rough weather. Both alternatives skip the recycled material story entirely.
The TNF Alta Vista comes close in weight class but lacks the same eco focus. Rab built this jacket around recycled fabric from the start. That choice shows in every stitch and seam.
The Arc’teryx Versalite uses Gore-Tex technology for superior condensation control. This makes sense for serious mountaineers facing extreme conditions. Most day hikers will not need that extra protection.
This jacket shines brightest for casual and moderate use. Think day hikes, weekend camping, and light trail adventures. It handles typical rain showers with confidence and ease.
Extended downpours or high output activities push this jacket toward its limits. The 2.5 layer build cannot match thicker alternatives during heavy exertion. Sweat buildup becomes noticeable on long, strenuous climbs.
Care matters with this jacket too. Avoid rough surfaces and sharp branches when wearing it. Treat the fabric gently to extend its lifespan naturally.
Buy this jacket if sustainability drives your gear choices. Buy it if lightweight packability tops your priority list. Skip it if you need maximum weather protection for extreme conditions.
The verdict comes down to matching needs with strengths. Rab created a jacket that performs well for its intended purpose. It does not try to be everything to everyone.
This focused approach works in its favor. The jacket excels at recreational hiking and casual outdoor pursuits. It falls short only when pushed toward extreme performance demands.
For the everyday hiker who cares about the planet, this jacket delivers genuine value. It proves that sustainable gear does not mean sacrificing comfort or function.
