    High Rise Heavy Absorbency

    I normally don't take the time to write reviews but these are fantastic! Recently went off my birth control so my period was super heavy and I have Lichen Sclerosus so it tends to get irritated down there with the use of tampons and pads but these undies are so absorbent, comfortable, and soft it's been a life saver! I was skeptical that they would be able to hold all of the flow through the night but i had 0 leakage at all. They're also very flattering and snatch my period bloat which who wouldn't that lol!
