🌊 The Outerknown Story: A Deep Dive into Sustainable Surfwear History

a couple of boats sitting next to each other

Every great surf story starts with a legend. In this case, it’s Kelly Slater. After decades of dominating the pro circuit and being the face of major surf brands, Slater saw a massive disconnect. The industry he loved, one so deeply connected to the ocean, was contributing to its destruction through wasteful production and questionable labor practices. He knew there had to be a better way.

In 2015, alongside creative director John Moore, Slater launched Outerknown. This wasn’t just another logo on a t-shirt; it was a statement. Their mission was audacious: to prove that you could create killer clothes without killing the planet. This move was one of the 8 Latest Surf Brand Marketing Strategies to Ride in 2025 🏄—leading with purpose and authenticity. They spent over two years researching and developing their supply chain before even releasing a product. That meant finding factories that upheld Fair Trade standards and sourcing materials that were either recycled, organic, or regenerative.

It was a bold, risky paddle-out into a crowded lineup, but it set a new high-water mark for what a brand in the Surf Fashion world could be.

🏄 ♂️ Outerknown’s Core Philosophy: More Than Just Clothes, It’s a Lifestyle

Video: OUTERKNOWN Blanket Shirt Review.

So, what’s the secret sauce that makes Outerknown… well, Outerknown? It boils down to a simple mantra: “For People and Planet.” Cheesy? Maybe. But they back it up with serious action.

  • Planet First: Their entire design process starts with the material. Can it be sourced sustainably? Is it durable enough to last for years, not just a season? They are obsessed with reducing their environmental footprint, from using buttons made of tagua palm nuts to ensuring their shipping is carbon neutral.
  • People Matter: This is huge. Outerknown is deeply committed to the people who make their clothes. By partnering with Fair Trade USA, they ensure that workers get fair wages, safe conditions, and community development funds. It’s about respecting the hands that craft the gear.
  • Style That Endures: This isn’t fast fashion. Outerknown designs are timeless. They create pieces you’ll wear for a decade, that get better with age, and that you can easily dress up or down. It’s the ultimate Surf Lifestyle uniform, built for comfort, versatility, and longevity.

They’re not just selling you a shirt; they’re inviting you into a community that believes in doing things the right way. But does the actual gear live up to these lofty ideals? Let’s get into it.

👕 Outerknown Product Deep Dive: Our Top Picks & Why We Love Them

Video: Outerknown Blanket Shirt Review.

Talk is cheap, but good fabric isn’t. We’ve put Outerknown’s key pieces through the wringer—from salty spray to repeated wash cycles. Here’s our honest breakdown of the must-have Surf Gear from their collection.

1. The Iconic Outerknown Blanket Shirt: A Surfer’s Best Friend

If Outerknown were a band, the Blanket Shirt would be its greatest hit. It’s the piece that put them on the map, and for good reason. It’s less a shirt, more a wearable hug.

Metric Surf Brands™ Rating (1-10) Notes
Design & Style 9.5 Timeless plaid and solid patterns. The definition of “effortlessly cool.”
Comfort 10 It’s in the name. Made from heavyweight organic cotton that’s unbelievably soft.
Functionality 9 Perfect as a standalone shirt or a light overshirt jacket. A true workhorse.
Sustainability 10 100% organic cotton, natural buttons. This is the gold standard.
Value 8.5 It’s an investment, but its durability and versatility make it worth it.

Our Take

We can’t overstate how much we love this shirt. It’s the first thing you reach for after a chilly morning session and the last thing you take off around the bonfire. As the reviewer in the featured video notes, it has an “8 out of 10 on softness” and is “extremely comfortable.” We’d even bump that up to a 10!

  • The Feel: It’s thick and substantial without being rigid. It drapes perfectly, giving you that relaxed, “I just came from the beach” vibe, even if you’re miles inland.
  • The Details: The buttons, made from tagua palm nuts, are a fantastic touch. It shows a level of detail and commitment to avoiding plastic that you just don’t see elsewhere.
  • The Fit: It runs a little big, designed for that comfortable, slightly oversized “overshirt” feel. The reviewer in the video, at 5’8.5″ and 191 lbs, found a Medium to be a great fit with minimal shrinkage. We agree—if you’re between sizes, you can likely size down for a trimmer look.

✅ The Verdict: An absolute must-own. It lives up to the hype and then some. It’s one of the most versatile pieces of clothing you’ll ever own.

2. Outerknown’s Sur Quarter Zip: Versatility for Every Adventure

Think of the Sur Quarter Zip as the Blanket Shirt’s slightly more athletic cousin. It’s that perfect layering piece for when you need a bit of warmth without the bulk.

Metric Surf Brands™ Rating (1-10) Notes
Design & Style 9 Clean, classic, and understated. Easy to layer.
Comfort 9 Made from a blend of organic cotton and recycled polyester, it’s soft and breathable.
Functionality 9.5 The perfect weight for a transitional layer. Great for travel.
Sustainability 9 Excellent use of organic and recycled materials.
Value 8 A premium price for a premium pullover, but the quality is undeniable.

Our Take

This is the ultimate “throw it in your bag” piece. Heading out for a surf check and the fog is rolling in? Grab the Sur Quarter Zip. Meeting friends for a casual dinner? It looks sharp over a tee.

  • The Fabric: The terry-like texture on the inside is incredibly soft against the skin. It wicks moisture well, making it a great post-surf option.
  • The Cut: It has a clean, modern fit that isn’t baggy but still allows for easy movement. The quarter-zip design lets you regulate your temperature easily.

❌ The Drawback? We wish it had pockets! It’s a minor gripe, but for a piece this versatile, a couple of hand-warmer pockets would take it to the next level.

3. The Woolaroo Jacket & Hoodie: Eco-Conscious Warmth for the Waves

When the temperature really drops, the Woolaroo series is Outerknown’s answer. Made from boiled merino wool, this isn’t your grandpa’s itchy sweater.

Metric Surf Brands™ Rating (1-10) Notes
Design & Style 8.5 Rugged, outdoorsy aesthetic. More functional than high-fashion.
Comfort 9 Surprisingly soft and non-itchy for wool. Naturally temperature-regulating.
Functionality 10 Incredibly warm for its weight. Wool is naturally water-resistant and odor-resistant.
Sustainability 9.5 Made with responsible, cruelty-free boiled merino wool.
Value 8 A significant investment, but it’s a piece of technical outerwear that will last forever.

Our Take

This is your shield against the elements. Boiled wool creates a dense fabric that blocks wind and resists water like a champ. It’s the kind of jacket you’ll have for years, and it will only look better with age. The natural antimicrobial properties of wool mean you can wear it all weekend without it starting to smell—a major plus for any surf trip.

4. Introducing the Odyssey CPO Jacket: Rugged Style Meets Sustainability

The CPO (Chief Petty Officer) jacket is a military-inspired classic, and Outerknown’s version, the Odyssey, gives it a sustainable twist.

  • The Material: Often made with a blend of recycled wool and other durable fibers, it’s built like a tank.
  • The Look: It’s a timeless silhouette that works as a heavy shirt or a light jacket. Think of it as a more structured, rugged alternative to the Blanket Shirt. We love the utility pockets and the clean lines. It’s a fantastic piece for anyone who appreciates heritage workwear.

5. Outerknown’s Apex Trunks: Performance Meets Planet-Friendly Design

Developed and tested by Kelly Slater himself, the Apex Trunks are the pinnacle of performance surfwear.

Metric Surf Brands™ Rating (1-10) Notes
Design & Style 9 Performance-focused cut with subtle, modern patterns.
Comfort & Performance 10 Ultralight 4-way stretch, welded seams to prevent chafing, quick-drying.
Functionality 9.5 The double-bonded butt seam is a game-changer for durability.
Sustainability 9 Made from over 90% recycled polyester from plastic bottles.
Value 8.5 Top-tier price for top-tier performance. For serious surfers, it’s worth it.

Our Take

These are, without a doubt, some of the best boardshorts on the market. You can feel the difference the moment you put them on. They’re incredibly lightweight and stretchy, moving with you without ever getting in the way. The welded seams mean no more rash after a marathon session.

The Question is: Do you need a boardshort this technical? For the casual beachgoer, maybe not. But for anyone spending serious time in the water, the comfort, performance, and durability of the Apex Trunks are unmatched.

6. Beyond the Basics: Outerknown Denim, Tees, and Outerwear Essentials

While the hero pieces get the spotlight, don’t sleep on their other offerings.

  • S.E.A. Jeans: Outerknown’s denim line is committed to sustainability, using organic cotton and production methods that use significantly less water. They also come with a lifetime guarantee—they’ll repair or replace them forever. That’s confidence.
  • Paz and Sojourn Tees: These aren’t your average tees. Made from organic cotton and hemp blends, they have a great texture and drape, and they hold up wash after wash.
  • Outerwear: From puffers filled with recycled materials to classic chore coats, their outerwear collection follows the same ethos of sustainable materials and timeless design.

♻️ Materials & Manufacturing: Outerknown’s Commitment to Sustainability

This is where Outerknown truly separates itself from the pack. They are transparent to a fault, and we love them for it. Let’s break down the building blocks of their gear.

Organic Cotton: The Foundation of Comfort

Almost everything you touch from Outerknown starts here. Unlike conventional cotton, which is a notoriously thirsty and pesticide-heavy crop, organic cotton is grown without harmful chemicals, promoting healthier soil and using far less water. It’s the reason the Blanket Shirt feels so ridiculously soft.

Recycled Polyester: Turning Trash into Treasure

This is pure alchemy. Outerknown takes discarded plastic bottles, breaks them down, and spins them into high-performance yarn for their Apex Trunks and other technical pieces. Every pair of trunks keeps about 25 plastic bottles from ending up in landfills or the ocean. ✅

Hemp & Other Innovative Fibers: Pushing the Boundaries

Hemp is a miracle fiber. It’s durable, breathable, and requires very little water or pesticides to grow. Outerknown blends it into their tees and other garments for a unique texture and added strength. They are constantly exploring other materials like regenerated nylon from fishing nets (ECONYL®) to push the boundaries of sustainable fashion.

Fair Trade Certified Factories: Ethical Production You Can Trust

This is non-negotiable for Outerknown. They work with factories that are Fair Trade Certified, which means they meet rigorous social, environmental, and economic standards. Workers are empowered, earn fair wages, and work in safe conditions. It’s a commitment to the human side of the supply chain that many other brands in the Surf Brand Guides overlook.

🤝 Outerknown’s Community & Collaborations: Making a Difference

Video: Brands You Need To Know: Outerknown.

Outerknown’s impact goes beyond the clothes they make. They’re actively involved in building a better community and pushing the sport of surfing forward.

Brother Benno’s & Beyond: Giving Back to the Community

Outerknown regularly partners with local organizations and non-profits. Initiatives like their work with Brother Benno’s, a foundation supporting the homeless in San Diego County, show a genuine commitment to their local communities. They often run campaigns where a portion of proceeds goes directly to environmental or social causes.

Surf Ranch Test Events & Athlete Partnerships: Pushing Performance Limits

Having Kelly Slater as a founder gives them the ultimate R&D lab: the Surf Ranch and the world’s best surfers. They use these connections to test their gear in the most demanding conditions imaginable. This ensures that products like the Apex Trunks aren’t just sustainable—they perform at the highest level of the sport.

🤔 Is Outerknown Worth the Investment? Our Honest Take

Video: Behind The Brand: Outerknown.

Let’s address the elephant in the room: Outerknown is not cheap. So, is it worth the premium price tag?

Our team’s consensus is a resounding YES, but with a condition.

You have to know what you’re buying. You’re not just paying for a shirt; you’re investing in:

  • Superior, sustainable materials that feel better and last longer.
  • Ethical manufacturing that supports workers and their communities.
  • Timeless design that won’t go out of style next season.
  • Unmatched durability, especially with programs like the lifetime guarantee on their S.E.A. Jeans.

If you’re used to fast fashion prices, you will experience sticker shock. But if you embrace a “buy less, buy better” philosophy, the cost-per-wear of an Outerknown piece is surprisingly low. That Blanket Shirt you buy today will still be your favorite thing to wear five, even ten years from now. Can you say that about the cheap flannel you bought at the mall?

  2. Start with a Hero Piece: If you’re new to the brand, start with what they do best. Grab a Blanket Shirt or a pair of Apex Trunks. You’ll immediately understand the quality and feel of the brand.
  3. 👉 Shop the Sales: Outerknown has a Men’s Sale and Women’s Sale section on their site. It’s a great way to snag their premium gear at a more accessible price point.
