STANDARD 100 BY OEKO-TEX®
This product has been verified in an independent laboratory and tested for harmful substances according to STANDARD 100 by OEKO-TEX®, an international association that ensures a high-level of safety from harmful substances in textile products. #20.HUS.16322 (Hohenstein HTTI)
Comfortable and they work. Also nice under a dress to provide coverage and avoid chafing, all while not worrying about leaking.
The sleep shorts are a total life-saver. So comfy and did not leak at all!!
I would definitely purchase again, they are very comfortable!
How much blood do your sleep shorts absorb?
Our Sleep Shorts absorb about 71 mL (roughly the amount held by 6-10 regular tampons) of blood. However, absorption is affected by many things, including your menstrual flow, position (sitting, standing, moving) and activity.
Can this be used for incontinence?
Our Sleep Shorts are designed specifically for periods and haven't been tested for use with light bladder leaks or incontinence. We are considering underwear for incontinence in the future, so stay tuned.
Do they shrink?
If cared for as directed, your underwear will not shrink. We suggest rinsing in cold water, machine washing on the cold/delicate cycle, and line drying or laying flat.
I have heard that some garments and textiles contain PFAS. Does your underwear contain PFAS?
No, our underwear does not contain PFAs. Our underwear materials are certified Standard 100 by OEKO TEX (TM), an international association that ensures a high level of safety from harmful substances in textile products. There are many different types of PFAS (Per- and polyfluoroalkyl substances).
OEKO-TEX tests for the most common PFAS in textiles as part of their certification process. In addition, Cora tests each lot of Period Underwear in the USA with a 3rd party lab to ensure compliance.
Learn more about Oeko Tex here. To reference the limit values and specific PFAS covered under the Standard 100 OEKO-TEX testing, see page 25, annex 4.
