FAQs

What you wear down there matters more than you think. Your underwear sits against your most delicate skin every single day, so what you're wearing ideally supports your body, not silently work against it.

Synthetic fabrics like polyester, nylon, spandex, and lycra might feel buttery soft, but beneath the surface they trap heat, block airflow, and carry hidden chemicals that can disrupt your hormones and microbiome. Over time, this can create the perfect storm for irritation, inflammation, and imbalance.

Switching to certified clean, natural materials isn’t just about comfort, it’s about protecting your health. Because peace of mind comes from knowing your body can breathe freely. You don’t have to wait for discomfort to make the switch. If you know it’s not good for you, that’s your sign to listen, and choose better for your body.

Seaweed is naturally rich in minerals, vitamins, antioxidants, amino acids and soothing properties that support your skin’s barrier and microbiome. Blended with Eucalyptus tree pulp, it creates a blend that’s antibacterial, breathable, and nurturing for your most intimate skin. You can learn more in our materials page.

SeaCell™ retains 88% of its skin-loving vitamins, minerals, and amino acids even after 50 washes. While its potency gently fades over time, it continues to nourish your skin with every wear. And even when the nutrients eventually wash out, your garment remains perfectly intact.

Our unique blend of fabric is designed to return to the earth without leaving a trace behind, including our novel 8% ROICA V550 degradable elastane.
