Period Underwear for Women Heavy Flow 5 Pack - 50ml Absorbency

In this review of TIICHOO period underwear, the bottom line is simple: these heavy flow panties are aimed at anyone who wants a reusable, comfortable alternative to pads for heavy days or overnight use. The single biggest reason to buy is the built-in 4-layer protection that is tested to absorb up to 50ml-roughly the equivalent of four tampons-so they can replace or back up disposable products during heavier menstrual flow, light bladder leaks, or post-baby bleeding.

Key Features

• 50ml absorbency: Tested to hold around 50ml of liquid, offering protection comparable to multiple tampons for heavy or overnight use.
• Four layered protection: A built-in multilayer lining helps trap fluid and reduce the risk of transfers to clothing or bedding.
• Full coverage gusset: Extended front-to-back coverage is designed to guard while sitting, lying down, or during activity.
• Soft rayon material: The fabric feels smooth and gentle on skin so menstrual days are more comfortable and less irritating than some synthetics.
• Reusable and PFAs free: These panties avoid PFAs and are machine washable, making them a sustainable alternative to disposables.
• Easy care: Wash cold after a soak; the maker recommends washing before first wear to help activate absorbency.

Who It's For

This pack is best for women and teens who experience heavy flow and want one underwear solution that works through the day, overnight, or as backup with a cup or tampon. It also suits people seeking a PFAs-free, reusable option to reduce disposable waste and long-term costs.

Those who should look elsewhere include people who require very high-volume clinical incontinence briefs or who need very loose-fitting underwear; some users find the fit snug and sizing can vary, so anyone who prefers a roomier cut may want to size up or try a different silhouette.

Pros & Cons

Pros

• Comfortable, soft rayon fabric that customers frequently describe as gentle on skin.
• Reliable absorbency for many users, with reports of working well throughout the day and saving money on disposables.
• Good full-coverage design that reduces the risk of stains on pants or sheets during sleep.
• Reusable and PFAs free, supporting sustainability and safer intimate wear.

Cons

• Sizing and leak resistance are mixed in reviews; some people report a very snug fit and occasional side leakage, so fit testing is important.
