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.

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 in comparison to synthetics. 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.

Our SeaCell™ fabric, ROICA™ V550 stretch fibre, and dyes are OEKO-TEX® Standard 100 certified, and the Organic Cotton is GOTS Certified at the mill level, meaning these materials have been independently tested for harmful substances before they're made into our underwear.

While the materials are certified, the finished Kiseau garment has not yet received separate OEKO-TEX® certification. We have begun the certification process and will share updates as we progress.

We believe transparency is essential, which is why we're always clear about what is and isn't certified. We only make claims that accurately reflect our supply chain, so you can make informed decisions with confidence.

Certifying a finished garment often requires more than using certified fabrics. Programs such as OEKO-TEX® and GOTS typically require certified manufacturing facilities, documented chain of custody, and ongoing third-party audits throughout production.

For many small, independently owned manufacturing studios, obtaining and maintaining these certifications can be prohibitively expensive. We chose to partner with ethical, small-batch manufacturers because of their craftsmanship and values, even though these certifications aren't always financially accessible for them, and we keep our supply chain transparent.

Our priority is always to invest in what directly touches your skin first: high-quality certified fabrics and dyes, while supporting ethical manufacturing partners that produce in small batches.

As we grow, we are pursuing additional certifications for our finished garments. Until then, we'll continue to be transparent about what is certified, what isn't, and why. We believe honest communication is just as important as the certifications themselves.

Very soft and comfortable! Feel so good knowing the fabric is not just safer than plastic/polyester but also good for my skin, and feels good.

The Cheeky Wins

I own every style Kiseau makes, and the cheeky wins. It sits broader across the hips and feels incredibly comfortable. I'm genuinely obsessed and have moved my whole rotation over to theirs. Pricey, but so worth it.

Sits Right Where I Want

I like my underwear to sit just on my belly button, and the cheekies hangs out right where I want it. I'm between a small and medium, so I bought both; I'm finding the small works best the more I wear it, while the mediums have become my lounge pairs.

I Adore My Cheekies

I adore my Kiseau cheekies. Both the fabric and the cut are really comfortable, and I love how breathable they are.

I had my doubts early on, mostly because it's such a new brand, but their customer service was great and their bikini style has slowly become my favorite pair in my underwear drawer.

Prefers The Larger Size

Lovely soft, comfortable fabric. I got a couple of mediums and several larges to compare, and while the medium is fine, I prefer the larger, since I dislike elastic that digs into me.

Lovely, But I Sized Up

The fabric feels lovely, and it's durable too. I ordered a size up from what fits me best, so I'll buy more in the right size.

Misses The Elastic-Free Version

I owned the bikini style already from collection 1, but not the biggest fan of the new elastic. I loved the old one because it was elastic-free. The fabric however is still unbelievably soft.

Among the comfiest pairs I've owned in my 40 years of shopping undies. I was skeptical at first, but they've been great.

Right For My Stage Of Life

These have completely changed things for me. I'd struggled to find something comfortable, light, and right for my stage of life. Still in my old brand, I wanted something sturdier that didn't read as dated. These are high quality and feel so soft. Thrilled it's a Canadian owned brand. They're going places!

Feeling Luxe

It took me a hot min to rationalize dropping so much money on a pair of underwear but like the fit is pretty insane. My cooch is feeling luxe let me tell you.

An Everyday Game Changer

Total game changer. Breathable, comfy, and a cute fit. I'll definitely grab another set. The brief and cheeky are my everyday go-to, and I save the thong styles for workouts; there's none of that sticky feeling afterward. With loads of hiking planned this summer, I'm curious how well they'll hold up.

My Everyday Winner

I ordered the discovery set to find which suited me best. They're all really soft and comfy, though the cheeky wins as my everyday pair.
