Review: Best period underwear - These are the best period panties I've tried. They are comfortable and not too thick. They absorb well and fit nicely with no VPL. I've not had any leaks with them. Decent price for such a good product.
Review: Comfortable and Effective - Age and hormones have made these a necessity. They are amazing, and I ordered a few pairs to use daily, but especially when traveling. Highly recommend. Sizing seems a little big to me.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best period underwear
*by A***A on June 25, 2025*

These are the best period panties I've tried. They are comfortable and not too thick. They absorb well and fit nicely with no VPL. I've not had any leaks with them. Decent price for such a good product.

### ⭐⭐⭐⭐⭐ Comfortable and Effective
*by D***O on October 6, 2025*

Age and hormones have made these a necessity. They are amazing, and I ordered a few pairs to use daily, but especially when traveling. Highly recommend. Sizing seems a little big to me.

### ⭐⭐⭐⭐ Good for light days only
*by B***Y on February 18, 2026*

I enjoy the fabric quality, but these are meant to be a backup to protect from leakage seeping into your pants. It is NOT one to free bleed into unless it is a very light day. I also don’t dare wear them if I’m heavy even when paired with a tampon or cup. This is for my last day only but are lightweight and comfy to sleep in too. I can wear them comfortably around the house, but if I am going to workout, I take them off because the pad portion isn’t as flexible and following the body as I would have liked. If you are looking for thick protection, this pair might not be for you. But if you want just a lightweight backup that isn’t tight on you, you can give it a try if it’s within the budget.
