Heavy (Medication Induced)

I am on blood thinners, which causes my period to be 100 times heavier. I've struggled for the past year to find products that can keep up and, most importantly, not leak. I can only wear a super absorbent tampon with a thin pad liner for 30 or less minutes at a time because my flow is so heavy. i had to resort to gigantic heavy flow pads with a tampon during the day and super super large thick pad with double panties overnight. Even with that, i leak. Not to mention the bulky discomfort of the pads At first, i was skeptical because these actually looked and felt like regular underwear. i couldn't wrap my brain around how on earth this underwear would hold so much liquid. I love these period underwear. it has answered my prayers!!! i dont need to worry anymore about being out and about and leaking. i even wore them out one night dancing on one of my heavy days! i really can't believe this. I've bought 2 more since and even got some for my sister who is struggling with incontinence after having her baby. They are awesome! Sizing is interesting. I saw 1 reviews regarding sizing being too small so I got an xl and it fits non snug. ( im normally a large) my sister is way bigger than me and she said the xl was just fine! i think the material stretches fine and gives in the right places without cutting off circulation or making you feel uncomfortable. im 150 my sister is 200 both of us tall

Great for school days and peace of mind

I bought these for my 11-year-old daughter and they have been a huge help, especially for school. It honestly beats having her change a pad throughout the day. With her flow, these keep her protected until she gets home, which gives both of us peace of mind. She also has sensory issues, and pads just didn't work for her. She told me these feel really comfortable and just like regular underwear, which is a big win for us. Definitely recommend for younger girls, especially if they struggle with traditional products.

Just try them.. you'll love it!

I was a bit worried because I've never tried a “reusable” pad before but THESE, THESE are the truth. Perfect for the beginning %26 end (especially at the end when I think it's done and BAM, SURPRISE!) I also love wearing these for overnight protection so I don't leak. I'll be buying these over pads forever now!
