2025, The Sealskinz Way
Taking a look back on a massive year for Sealskinz!
In an ever-evolving world, 2025 stands out as a defining year for us at Sealskinz. It was a year that saw the brand expand beyond product innovation alone, deepening our connection with community, pushing forward with sustainability, embracing meaningful collaborations, and continuing to redefine how people experience the outdoors, whatever the weather. From London run routes to global partnerships, from sustainable apparel to heated technology and kidswear, 2025 marked a year of momentum, one grounded in Sealskinz’s heritage but firmly focused on the future.
The Hinde Street Run Club
If there’s one thing 2025 proved, it’s that Sealskinz isn’t just about products, it’s about people. The launch of the Hinde Street Run Club brought that ethos to life in the heart of Marylebone. Heralding from our flagship store on 1 Hinde Street, our run club has quickly become a highlight of the month.
More than just a place to clock miles, the Hinde Street Run Club has become a community hub where runners of all levels come together under the shared banner of outdoor connection and encouragement. Each session, typically covering 5km and 7km routes through Regent’s Park and the surrounding streets, is welcoming, inclusive, and free. Runners gather for warm-ups, connect over shared passion, and benefit from expert talks, stretching sessions, and post-run camaraderie thanks to local business partnerships. We've even had the privilege of hosting events with other Marylebone based businesses ranging from our first ever Marathon Training Panel with Spacemade and At the Core, to our Italian themed run club with Prezzemollo and Vitale!
Whether you’re a newbie on their first 5K or a seasoned runner pacing alongside friends, the Run Club embodies our mission to help people “stay outdoors longer”, not just through gear, but through shared experience.
Worn by Weather
For over 25 years, we have built our reputation on technical waterproof accessories that stand up to the harshest elements. But in 2025, we took the bold step forward by launching our first complete men's and women's sustainable outdoor clothing range: Worn by Weather.
This collection represented more than a new category; it was a reimagining of what performance apparel should be in an era of rising environmental awareness. Designed to enable wearers to stay outdoors longer, whether hiking rugged trails, camping by a lake, or simply navigating daily life, every piece in Worn by Weather has sustainability embedded in its DNA.
At the heart of the range are versatile pieces like our bestselling waterproof packable jackets, fleeces with waterproof chest pockets, and water-repellent trousers built for temperamental conditions. T-shirts crafted from organic cotton with UPF sun protection add comfort and conscience to everyday use.
Importantly, the collection’s reliance on recycled and responsibly sourced materials reflects a larger commitment to durability and circular design, reducing waste, conserving energy and water, and respecting the wild landscapes that inspire us at Sealskinz in the first place.
In the words of Creative Director Ray Kelvin, our Worn by Weather collection wasn’t just gear, it represented the next stage of Sealskinz’s journey: “gear that performs, protects, and gives back.”
Giving Back to the Outdoors: Partnering with Greenspark
Alongside product innovation, 2025 saw Sealskinz deepen its commitment to environmental stewardship through its partnership with Greenspark, an organisation focused on large-scale reforestation and community uplift.
Under this initiative, every Sealskinz Worn by Weather clothing order now contributes to real-world impact: trees planted, ecosystems restored, and livelihoods supported in the mangrove forests of Kenya’s Mteza Creek. This project not only sequesters carbon but also supports local economies with paid work, biodiversity enhancement, and coastal protection efforts.
The significance of this partnership goes beyond a simple carbon offset, it reflects a growing belief within Sealskinz that protecting the outdoors must be paired with empowering the communities that live in and around these environments. It’s one thing to make a jacket that withstands the wind; it’s another to help ensure that the forests and wetlands we explore remain vibrant for generations to come.
The Launch of our First Kidswear Range
2025 also marked the launch of our first kids’ collection, a significant step in bringing the brand’s trusted protection to the next generation of outdoor explorers.
Designed to perform just as relentlessly as Sealskinz’s adult accessories, the kid’s collection features a focused range of waterproof socks, gloves and hats, engineered for comfort, durability and all-weather play. Built using our three-layer Aquasealz™ waterproof construction, each piece keeps children warm and dry without bulk or irritation.
Bright colourways and playful designs encourage confidence outdoors, while practical features such as wind resistance, machine washability and robust construction ensure the range can withstand the realities of childhood adventure.
Captured by the campaign tagline “Let them splash, let them play and let them explore”, the kids collection reflects our belief that the outdoors should never feel off-limits, no matter the weather, and no matter your age.
Collaborations: LeMieux and Simms
Collaboration played a pivotal role in 2025, as Sealskinz joined forces with two globally respected performance brands: Simms and LeMieux.
The Simms x Sealskinz collaboration brought together two leaders in technical outdoor performance. Designed specifically for anglers and waterside environments, the collection combines Simms’ deep expertise in fishing gear with Sealskinz’s advanced waterproof technologies. Products such as gloves and socks engineered for submersion and prolonged exposure demonstrate how shared knowledge can result in truly specialist performance gear.
Meanwhile, the partnership with LeMieux extended Sealskinz technology into the equestrian world. Waterproof riding gloves and accessories were designed to meet the demands of riders who spend long hours outdoors, offering grip, warmth and protection in challenging conditions.
Together, these collaborations showcased Sealskinz’s versatility, proving that its proprietary technologies can enhance performance across disciplines while maintaining the brand’s commitment to quality and innovation.
Expanding our Range
Rounding out 2025 was the continued expansion of our full accessory range. From our new slippers flying off shelves, to bag and underwear collections dropping, and even advances in our heated element technology, we continue to push the boundaries of what outdoor gear can deliver.
Products such as the Holt and Sandringham Women’s Water-Repellent Heated Gilets combine water resistance with integrated heating, offering adaptive warmth in colder conditions.
By blending active heat with technical fabrics, we are redefining comfort, transforming protection from something passive into something responsive.
Similarly our Stowbridge automatic heated gloves made advances for extreme cold weather. With an automatic switch for instant heat in colder temperatures, Stowbridge has protected many a hand this year from those with Raynauds to those skiing, dog walking or cycling in colder temperatures this winter.
These innovations underline the brand’s commitment to evolving alongside the needs of modern outdoor life.
Here's to 2026!
2025 was a year of progress, purpose and confidence for Sealskinz. From community initiatives and sustainable design to collaborations, kidswear and cutting-edge technology, the brand has continued to evolve without losing sight of its roots.
As Sealskinz looks ahead, one thing remains clear: the mission to help people stay outdoors longer is stronger than ever, driven by innovation, shaped by community, and inspired by the weather itself.
So a massive thanks to everyone involved with our mission this year, and here's to a fantastic 2026!
