Are your leggings made with toxic forever chemicals? Your workout should push the limit, not your health. That’s why new Seissense athleisure is crafted without PFAS, the so-called “forever chemicals” linked to lasting harm in people and the planet. Designed to perform as hard as you do, Seissense keeps toxins out of your body and out of the environment, so every stretch, sprint, and sweat is clean and healthy for your body. All while looking good in high-performance, stylish designs that are consciously made using sustainable materials.
Unlike many other athleisure brands, Seissense is completely free of PFAS, otherwise known as “forever chemicals” that have quietly infiltrated many other popular performance wear brands. These chemicals do not break down in the environment and can accumulate in living organisms, including humans. There has been much research linking PFAS exposure to health problems such as liver damage, thyroid disease, obesity, fertility issues and cancers (1, 2, 3, 4, 5).
Seissense – pronounced “Sea Sense” has launched a 50+ piece collection, including leggings and swim, that marries sleek design with responsible manufacturing.
In addition, all Seissese pieces are crafted with technical precision, from Fuze Tech – a chemical-free, bacteria-busting solution that keeps clothing fresh – to collagen-infused fabrics. Seissense is produced in OEKO-TEX® and B Corp-certified facilities, ensuring workers are paid properly and the planet doesn’t pay the price.
Dr Naomi Newman-Beinart says: “There has been a growing interest in non-toxic and sustainable leggings. Demand for healthier, eco-conscious alternatives is rising notably, with health and safety concerns fuelling demand. Rising awareness of PFAS, or “forever chemicals”, in conventional activewear, especially in sensitive intimate areas, has made toxic and forever chemicals-free options more appealing.”
Are your leggings toxic? Testing found fluorine (an indicator of PFAS) in women’s sportswear from popular brands like Old Navy and Lululemon, and non-toxic leggings are definitely becoming more popular, as consumers prioritise health, environmental responsibility, and sustainable innovation.
About the collection: The collection is built across four considered pillars: Essentials for daily training and lounging, Seasonal Drops featuring hand-illustrated prints,
Active Swim designed for real movement in the water (SPF 50+ included), and a Lifestyle Capsule built for the between-times: travel, recovery, and everyday life.
“After years of careful planning, design, refinement, and overwhelming early interest in select styles, we think we have truly created the ultimate athleisure brand”, said a spokesperson from the brand. The company name, a blend of ‘sense’ and ‘essence,’ reflects this dual commitment to design integrity and social responsibility. “It felt impossible to find clothes that looked great, performed well, and were also genuinely kind to both the planet and to those wearing them, so we decided to make them ourselves. We wanted to feel good in them and good about them,” said the team.
Every purchase sends £1 to Ripples Africa via Nourish Fund UK, helping build water wells in Malawi.

2. Immune System Effects PFAS exposure reduces the effectiveness of vaccines in children by weakening the immune response. Grandjean et al., 2012, JAMA. Classified as immunotoxicants by the U.S. National Toxicology Program.
3. Cholesterol & Metabolic Disorders. PFAS exposure is strongly associated with elevated cholesterol (especially LDL cholesterol). Nelson et al., 2010, Archives of Internal Medicine. Evidence also suggests increased risk of liver damage, fatty liver disease, and metabolic dysfunction.
4. Thyroid & Hormone Disruption. PFAS interfere with thyroid hormone regulation, leading to hypothyroidism in adults and developmental issues in children. Knox et al., 2011, Environmental Health Perspectives
5. Reproductive & Developmental Issues. Linked to reduced fertility in women, lower sperm quality in men. Pregnancy risks: preeclampsia, hypertension, low birth weight, developmental delays. Stein et al., 2009, Environmental Health Perspectives
