Synthetic clothing is cheap but come at a cost.
Chemical leaching: Polyester, nylon, and spandex are plastic-based. They can contain residues from dyes, finishing chemicals, flame retardants, and PFAS (“forever chemicals”) that may transfer through sweat and friction.
Odor trapping: Synthetic fabrics hold onto sweat smells even after washing.
Microplastic buildup: Studies show microplastics in human blood, lungs, and placentas — meaning this isn’t just an ocean problem, it’s in us.
Everyday effect: People with sensitive skin often notice rashes, acne, or eczema flare-ups when wearing synthetic fabrics compared to natural fibers like cotton or merino.
Oil-based clothing origins:
Synthetic takeover: Polyester, nylon, and spandex make up nearly 98% of activewear.
Polyester and nylon are made from petroleum—every gym shirt starts as crude oil.
In our food chain: These plastics accumulate in oceans, fish, and ultimately inside our own bodies.
The textile industry is a major carbon emitter, and synthetics drive that footprint.
85% of clothing in the U.S. ends up in landfills, and synthetics take hundreds of years to break down
Plastics reduce sperm quality.
Toxins from synthetic fabrics leach into the skin and bloodstream, harming fertility and long-term health.
Plastics disrupt your hormones.
Microplastics and chemical additives act as endocrine disruptors, interfering with natural balance.
Plastics trap odors.
Synthetic fibers absorb sweat and bacteria, making smells harder to wash out.
Why Switch to Merino?
Plastic-free: No polyester, nylon, or spandex so you’re not wearing oil on your skin.
Naturally odor-resistant: Merino stays fresh for days, unlike synthetics that trap sweat stink.
Breathable & temperature-regulating: Keeps you cool when it’s hot, warm when it’s cold.
Biodegradable: Returns safely to the earth instead of lingering for centuries in landfills.
Safer for your body: No hidden PFAS, phthalates, or microplastics leaching into your skin.
Peace of mind: Choosing merino means healthier workouts, healthier oceans, healthier you.
