A pair of swim trunks doesn’t usually make you think about ocean pollution, but that’s exactly the connection Fair Harbor set out to build. Founded by a sibling duo who grew up watching plastic wash up on their favorite beach, this brand has turned tens of millions of recycled bottles into genuinely comfortable, stylish swimwear. Here’s a full breakdown of what makes Fair Harbor different, how the products perform, and whether it’s worth buying.
What Is Fair Harbor?
Fair Harbor is an American coastal lifestyle and swimwear brand founded in 2014 by siblings Jake and Caroline Danehy, inspired by summers spent at Fair Harbor, a beach community on Fire Island, New York. Caroline started the company with her brother while she was still in high school, driven by what they’d witnessed growing up: a shocking volume of plastic pollution washing up on the beaches of their childhood vacation spot. That firsthand experience shaped the brand’s entire mission from day one, keeping shores clean and plastic out of waterways while offering customers genuinely great swimwear at a fair price.
The brand’s business model centers on transforming recycled plastic bottles into fabric for its swimwear and apparel, with each suit typically made from anywhere between 3 and 22 recycled bottles depending on the specific style. Since launching, Fair Harbor has grown substantially, reporting sales growth of more than 1,000% year-over-year in its early years, and the brand has since become a Certified B Corporation, repurposing more than 37 million recycled bottles and other sustainable fabrics into its expanding product lineup.
What Makes Fair Harbor Different?
- Recycled plastic bottle fabric — Fair Harbor’s core swimwear is made largely from recycled polyester and nylon spun from plastic bottles, directly tying each purchase to reduced ocean plastic waste
- Signature BreezeKnit liner — rather than the scratchy mesh lining common in most swim trunks, Fair Harbor developed a soft, chafe-free BreezeKnit liner, addressing a widely shared customer complaint about typical swimwear
- Certified B Corp status — Fair Harbor has earned B Corp certification, reflecting independently verified standards around environmental and social responsibility, not just self-reported sustainability claims
- Nonprofit partnerships — the brand partners with ocean-focused nonprofits like the Surfrider Foundation, tying its business directly to broader environmental advocacy efforts
- Genuine sibling-founder story — Jake and Caroline Danehy built the company together while still young, both under 30 in the brand’s early growth years, giving Fair Harbor a distinctly personal, mission-driven founding narrative
- Expansion into year-round essentials — while swimwear remains core to the brand, Fair Harbor has expanded into everyday apparel designed with the same durable, sun-and-salt-tested philosophy

Is Fair Harbor Good Quality?
Fair Harbor has built a strong reputation specifically around solving a common swimwear complaint: uncomfortable, chafing mesh linings. Independent reviewers who’ve tested the brand’s trunks directly have generally responded positively, highlighting the BreezeKnit liner’s soft, underwear-like feel as a genuine improvement over typical swim trunk construction, along with praise for the brand’s use of DWR (durable water repellent) treatment for quick drying.
Beyond comfort, Fair Harbor’s sustainability credentials are independently verified rather than just marketing language, reflected in its B Corp certification and documented use of recycled materials, sourced through manufacturing partners who are also vetted for worker safety, fair wages, and environmental impact standards. Most styles run true to size, though the brand notes that tees and casual shirts are cut more relaxed, suggesting sizing up if you’re between sizes on those specific items.
Fair Harbor’s Environmental Impact
A defining part of Fair Harbor’s identity is the direct, quantifiable connection between its products and ocean plastic reduction. With more than 37 million recycled bottles and sustainable fabrics repurposed since launching, and individual swimsuits typically containing somewhere between 3 and 22 recycled bottles depending on the style, the brand offers customers a genuinely measurable environmental impact tied to each purchase, rather than a vague sustainability claim. This focus has remained consistent since the company’s earliest days, when founders Jake and Caroline Danehy built their entire business model around using ocean-bound plastic as a raw material rather than treating sustainability as an add-on feature.

- Order your usual size for classic swim styles, since most Fair Harbor swimwear runs true to size
- Size up on tees and casual shirts if you’re between sizes, since these run more relaxed than the brand’s swim trunks
