Recommended: Machine wash on a gentle cycle, or handwash using natural detergent inside a delicate wash bag.

Avoid: Bleach and fabric softeners. They break down natural fibers and shorten the life of your undies.

Drying: Tumble dry on low, or better yet, lay flat or hang to air dry for maximum longevity.

Storage: Keep your undies in a cool, dry place. In humid environments, a dry storage bin with a bit of baking soda helps keep things fresh.

Comfort Guarantee: If the fit isn't right, contact us within 21 days of delivery for an exchange or store credit. Applies to single items only (not bundles, sets, or multipacks), and excludes bralettes, which are final sale. For hygiene reasons, opened underwear can't be returned, but your first item can be tried on risk-free.

Returns and Exchanges: We accept returns and exchanges within 21 days of delivery for unopened items in their original, intact packaging. Bralettes are excluded.

Final Sale: Bralettes are final sale and not eligible for returns or exchanges. This includes sitewide sales, select sets, and holiday sales.

FAQs

There are many reasons natural underwear is better for intimate health. Natural fibers are breathable and help keep the intimate area cool, dry, and balanced. Synthetic fabrics, by contrast, can trap heat and moisture, potentially disrupting pH and the microbiome. For a deeper look at the science behind this multi-layered topic, we invite you to explore our blog.

Every pair of Kiseau undies begins with a custom blend of certified organic, non-toxic fabrics, infused with seaweed. High quality natural fabrics are inherently more expensive compared to synthetics like lycra, nylon, spandex or elastane.

Our undies are hand made in small batches by human beings we know. People who are paid fairly and work in safe, respectful environments.

By making a conscious decision to stay away from plastic in our supply chain from product to packaging, we're one of the pioneers in the alternative underwear space, which means our production comes at a premium.

Switching to natural, organic, and non-toxic underwear is a powerful step toward supporting your natural microbiome. Our breathable, skin-loving fabrics are free from toxins, endocrine disruptors, and harsh chemicals, and may help reduce irritation or moisture buildup that can contribute to imbalance. That said, every body is beautifully unique. Factors like diet, lifestyle, hydration, and even laundry products can influence your intimate health, even if you wear non-toxic undies

Right here is a beautiful place to begin. The layer closest to your skin, worn all day every day, is one of the most meaningful switches you can make. Visit our Body Talks Blog for honest conversations with real women on hormonal health, conscious consumption, and living in tune with their bodies. Think of it as a softer, slower way in. No pressure, no perfection, just choosing better one small step at a time.

Our 7% non-toxic ROICA V550 is certified clean stretch unlike conventional elastane found in most underwear. It's just enough to hold shape and move with you while still meeting our strict non-toxic standard. Our mission is to become a fully plastic-free, 100% natural brand, as we keep up with new material sciences.
