I prefer natural fibers to synthetic fibers...and organic cotton to tencel. The brand I had landed on during my previous search (Lunapads) rebranded to Aisle + now uses a tencel/organic cotton blend rather than organic cotton. This is still preferable to the vast majority of other period underwear brands who use synthetic materials, but it prompted me to do a little bit more investigating.
Not only are synthetic fabrics oil derived, they do not biodegrade. Synthetic fibers produce plastic microfibers that end up in oceans, air, fish, drinking water + even in our blood. Years ago, when synthetic period underwear were the only option, I tried some + found the synthetic fabrics too compressing for my crampy periods...and sweaty too.
Period has some organic cotton offerings, but the absorbency level I wanted did not have a corresponding natural fiber option. When I asked about the working conditions of their garment workers, I received a very polite response that they did not know...but should maybe look into that. I gently encouraged them to do so, especially since period products are inherently connected to women + most garment workers are women.
I really like the ones I bought. I've used the first one I purchased for a month + would truly wear them any day of the month. They are that comfortable + work as I depend on them to do too.
I would love to have found some completely compostable, comfortable, effective, leak-proof underwear priced + sized for everyone...and made from American-grown, organic cotton, spun + sewn close to the farm...with all those involved in the supply chain receiving fair wages + healthy working conditions. As usual, I'm doing the best I can for now.
