Seissense, pronounced ‘sea sense’, has launched in the UK, positioning itself as a challenger brand in the performance apparel and activewear space.
After two years of extensive development, the new performance wear label is launching with a 50+ piece collection, available exclusively online.
The collection spans four pillars, including:
- Essentials: Everyday performance wear for gym and outdoor enthusiasts. These form the foundation of Seissense’s tonal garments designed for performance and all day comfort. Includes supportive and sculpting leggings, performance tops, and support sports bras.
- Seasonal Drops: Limited edition pieces featuring hand illustrated artist prints. These capsule collections aim to offer a fresh visual identity while maintaining technical performance features.
- Active Swim: Swimwear designed to handle workouts and open water swims with added SPF 50+ protection and chlorine resistance.
- Lifestyle Capsule: Includes technical dresses with breathable, relaxed silhouettes, for post-workout, recovery, travel and as a daily staple.
A Seissense spokesperson said “We’re incredibly excited to launch Seissense, after years of careful planning, design, and refinement, and overwhelming early interest in select styles, we think we have truly created the ultimate activewear brand.
“Seissense was born with intention. It was impossible to find activewear that looked great, performed well, and was also genuinely kind to both the planet and to those wearing it, so we decided to make it ourselves.
“The brand name combines both ‘sense’ and ‘essence’ to convey its commitment to purpose in everything we do. Brands often neglect ethical production and sustainable methods in favour of performance or margins. Seissense doesn’t compromise on any of this, establishing a new benchmark within the industry and setting a challenge for other brands to keep up with.
“Every piece is made with premium fabrics, creative design and conscious production that also gives back. This is only the beginning of a very exciting journey ahead.”
Key fabric features include:
- Fuze Tech: A chemical-free antimicrobial technology that kills odour-causing bacteria on contact, keeping garments fresh for longer.
- PFAS-free: All Seissense activewear is free of harmful PFAS chemicals, known as ‘forever chemicals’.
- Collagen Infused Fabric: Offering softness, reduced chafing, and moisture-wicking properties.
- Sustainable Manufacturing: Seissense works with OEKO-TEX and a B Corp certified factory that prioritise fair wages and environmentally friendly practices.
In addition, Seissense has a philanthropic focus, donating £1 from every purchase to Ripples Africa via Nourish Fund UK, which builds wells to provide access to clean water in the Malawian Lake Community.
“Making a positive impact is foundational to our brand,” added the Seissense team. “It’s not just about creating great products, but using our platform to create change in the world, and that’s why our pay it forward approach is at the core of what we do.”
