In Crosshaven, Co Cork, McWilliam Bags has been crafting durable, iconic holdalls from sailcloth since 1971. Now a Certified B Corporation™, the brand blends heritage, sustainability and design.
Some brands are born from a trend. Others from necessity. McWilliam Bags belongs firmly to the latter, a label shaped by Ireland’s maritime culture, with a legacy of craftsmanship that has weathered decades of change while staying true to its roots.
Founded in 1971 in Crosshaven, Co Cork, McWilliam began not as a bag company at all, but as a sailmaker. Its original purpose was practical: producing hard-wearing sails that could withstand Atlantic conditions. Then the team began using leftover sailcloth to make bags which were practical, durable and instantly recognisable with their colourful stripes.
So, what began as a sideline quickly became a signature, and the McWilliam bag was born.
The bold-striped McWilliam holdall, built from sail-grade materials, became a staple of Irish family life. Durable enough for weekends by the sea, distinctive enough to be spotted across airports and harbours, and humble enough to be passed from one generation to the next, the bags embodied something rare: a design that simply didn’t date.
Durability has always been McWilliam’s north star. Unlike disposable fashion, their bags are designed to endure. Each is still cut from square panels – a process inherited from sailmaking – which cleverly eliminates fabric waste. Even today, scraps are repurposed into smaller items, ensuring that nothing goes to waste.
The workshop also continues a tradition of repair. Customers can send bags back for repairs under the manufacturer’s guarantee if there are defects in materials or workmanship, and the company also offers paid repair services for certain issues, such as replacing zips or other accessible parts. These services demonstrate McWilliam’s commitment to extending the life of its bags and encouraging a more sustainable approach to design.
This mindset – make once, make well, make to last – is what has kept McWilliam relevant across half a century of change. And it’s what made them a natural candidate for B Corp Certification.
Today, McWilliam is part of a growing movement of design companies redefining what success looks like. Becoming a Certified B Corporation places them among a global community of 8,000 businesses, and one of only 85 in Ireland, that meet rigorous standards for social and environmental impact. Unlike a simple label, B Corp is a framework for accountability. Every three years, companies are reassessed against even higher standards. It’s not about saying “we are sustainable”, it’s about proving it, consistently.
For McWilliam, certification formalises what they’ve always practised: designing responsibly, caring for their people and leaving the planet better than they found it.
Sustainability at McWilliam doesn’t stop at materials; it extends into the very fabric of the community and culture the brand supports. The company has already transitioned to plant-based PVC and continues to experiment with new, eco-friendly fabrics that push the boundaries of responsible design. Every purchase made contributes directly to ocean conservation through their partnership with EcoDrive/4ocean, ensuring that the impact of each bag goes far beyond the workshop.
At home, McWilliam is equally committed to its people, paying all employees at least a living wage, providing private health insurance, and fostering a culture of care that prioritises wellbeing. Even outside of the workplace, the team gives back, volunteering with the RNLI lifeboat service – a gesture that feels fitting for a company so deeply rooted in Ireland’s maritime traditions. Together, these commitments illustrate McWilliam’s holistic approach: sustainability here is not a department or a campaign, but a set of values woven into every decision the business makes.
For owner Claire Morgan, certification is both a validation and a challenge.
“B Corp is proof that business can be a force for good,” she explains. “It validates where we’ve come from and pushes us forward to keep improving for our people, our community and our planet.”
That spirit of accountability defines the road ahead. McWilliam is now focused on publishing its progress, setting ambitious new goals and keeping itself open to scrutiny from its community. In other words, this is less about what they’ve achieved and more about what they’ll do next.
For the wider design community, McWilliam’s journey offers a lesson. Good design is not only about form and function; it’s about responsibility. A McWilliam bag is beautiful, yes, and practical, undeniably. But what elevates it is the story. It is of sails reborn as holdalls, of scraps turned into accessories, of products repaired instead of discarded, of a company daring to measure itself not just by profit, but by impact.
It’s a reminder that design doesn’t have to compromise. When sustainability is part of the creative process, the result is something timeless.
McWilliam’s B Corp Certification is a milestone, but it’s also just the next leg of a much longer voyage. The company is clear-eyed about its imperfections and committed to the work ahead. Customers, employees and partners alike are invited to join that journey, to carry not just a bag, but a piece of a movement towards a more responsible way of making and living.
After more than fifty years, McWilliam Bags remains what it always has been: a brand defined by craft, community and care.
Only now, its sailcloth stripes carry another meaning, a signal that design can chart a sustainable course, and bring us all along for the journey.
