Maker Story
Hello, we are FLOWS, a femtech sportswear brand specialized for women. Thanks to the support from our backers, we are launching an encore crowdfunding campaign. The Hidden Panty Leggings is FLOWS' first project, proposed as a solution to everyday discomforts that women commonly experience. We collaborate with a pattern director with over 30 years of experience, and manufacture 100% domestically in a Korean athleisure/underwear factory with over 30 years of expertise. The funds raised will be used for product development R&D, reflecting feedback from our supporters. We chose Wadiz because it is home to many supporters who have a high demand for fresh and innovative products.
Frequently Asked Questions
Q. Is there a reward configuration recommended by the maker?
A. For supporters who exercise 1-2 times a week,Daily Double + Liner Double configuration is recommended. For supporters who exercise regularly 3 or more times a week,Daily Triple or Penta+Liner Double configuration is recommended.
Q. Can I wear it during my period?
A. Hidden Panty Leggings are general consumer products, not medical devices, so we recommend using them together with menstrual products. The liner version leggings have absorption and leak-proof functions, so depending on your flow, you can use them alone or with pads. On lighter days, you can simply wear the liner leggings, and they are especially useful on days when you are unsure when your period will start. They can also serve as a backup when using tampons or menstrual cups, making them very suitable for period wear.
Q. I am concerned about the Y-zone fit. Is it okay to wear them?
A. If you wear the leggings at the correct rise, properly fitted,the Y zone Without worry Comfortably You can wear It But still If you are concerned In such cases, we recommend the liner version leggings. The absorbent pad provides support, allowing it to fit comfortably around the Y-zone and giving a covered feeling.
Q. Can I exchange or get a refund?
A.Due to the nature of the leggings fabric and hygiene issues, exchanges and refunds are difficult. Please check the actual size carefully before purchasing. We will assist with exchanges or refunds only for unworn products with the tag still attached. If there is a problem with the product, please contact our customer service center and we will assist you.
Q. I hear a popping sound when I wear it for the first time. Is it too small?
A. Due to the manufacturing process of integrated leggings, basting is included. The popping sound you hear at first wear is the basting thread breaking, which is a natural occurrence during initial use. You can wear it with confidence.
