From GOTS certiifed organic cotton to more innovative and sustainable fabric like these:
SeaCell™ Lyocell is an innovative and super sustainable fabric featuring seaweed
The seaweed used in the fabric is pure, sustainably harvested from the clean fjords of Iceland on a regenerative cycle that support the marine ecosystem. It is blended with sustainably sourced eucalyptus wood pulp from FSC certified responsibly managed forests.
This innovative fabric rich in antioxidants, vitamins, and minerals.
ROICA: sustainable elastane, which can degrade in 2-3 years in industrial composting, compared to conventional elastane, which takes decades!
Kiseau is composed by 93% natural fibers and 7% bio-elastane. The amazing part is that SeaCell™ fabric is fully biodegradable, within 41 days, composting naturally and returning back to the Earth to boost the circle of life.
ROICA™ V550 (bio-elastane) is the a safer, cleaner alternative to conventional spandex and elastane.

🌿This is my latest discovery! Many are still promoting cotton underwear as a healthier or safer alternative to synthetics, but they are promoting pesticides. If your underwear is not certified organic, then you are putting pesticides on your skin! Then, many are not making the distinction of being 100% synthetic-free, since many still contain elastane, spandex, or other elastic materials. Lastly, the dyes can make perfectly organic cotton underwear not biodegradable! When looking at underwear, we need to take into consideration all of these!! 🌿 This organic underwear is made with organic cotton, SeaCell-certified fabric, OEKO-TEX certified dyes, and biodegradable elastane! This is what makes Kiseau different from other organic underwear brands: 🌿 SeaCell is made with wild Icelandic seaweed and FSC-certified eucalyptus pulp; this is very innovative, and it is like wearing nature! Much more sustainable and breathable on your skin compared to conventional elastane, plus it is rich in antioxidants, vitamins, and minerals. Making Kiseau a more sustainable and biodegradable brand! Compared to brands that use traditional elastane or spandex! Kiseau also chooses a more sustainable elastane version, ROICA, which can degrade in 2-3 years in industrial composting, compared to conventional elastane, which takes decades!
This brand is doing it all right!!!
