### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works Great, Super Comfortable
  

*by S***P on Reviewed in the United States on June 20, 2024*

Use these as a back up for my heavy days when I use a tampon. These are super comfortable, lightweight (not bulky like pads are), and I even machine wash them. High quality and stops any leakage.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for what I needed
  

*by R***E on Reviewed in the United States on April 14, 2023*

I was looking for something I could wear at night, I hate pads, feel like a diaper and I’m paranoid about getting TSS so no overnight tampons. Then there’s also those days when you’re not sure when your period is coming, I use these to prevent the frequent trips to the bathroom to check or having to wake up overnight. They are great for if you expect your period at work, traveling or overnight, I just pop these on and it takes the stress out of ruining a nice pair of underwear or clothes or an embarrassing accident. Once I got my period right as my flight was taking off. That’s finally what prompted this purchase! I travel frequently. I have used it for two periods now and just ordered a second pair. I’m hoping to minimize my use of tampons to just a few on my first day then use these underwear. I wouldn’t use them alone on day one but they are great as a safety measure. So far i really like them for what I needed, I think I will save money not having to buy as many tampons plus it’s better for the environment. These ones actually also look great great on. Love the lace detail. For reference I bought the Small and I have a waist of 26 and hip of 36 inches (actual measurements) I’m short waisted and 5’4”,the top of the underwear is about 4-5 inches below my belly button. It’s snug but comfortable. Hope this helps someone.
