About this item

Product details

I’m dedicated to giving you a good night’s sleep on your period. I have a built in five layer padding that absorbs vertical flow and horizontal flow, because when you sleep your period can flow a little differently and I want to make sure your night is leak proof. I’m made of soft organic cotton and am cozy, comfy and snug so you feel safe and secure and like you’re wearing a combo of your favorite leggings and PJs. I’m also great for those outrageous first heavy days, when if you have an option of laying on a couch all day, you take it. Sleep well. When to wear: on heavy nights, or very heavy days. Some customers report that this style runs a little small - we recommend sizing up if you are on the fence!

Reliable and Comfortable - Bye Bye Embarrassment

Prior to trying this set from the period company I had only ever used Knix which can cost about 2x what the period company does. I cannot say enough about how well these work. Postpartum, when my periods have been really heavy, I could not find any products that keep me comfortable through the night until I tried these. Being postpartum is challenging enough without worrying about if your period products will keep you protected throughout the night, and I no longer have that concern with these. I highly recommend these to anyone who menstruates, I wish I had found them sooner.

Get these!

Game changer for periods during the nighttime. I did size up to a 2X, usually wear XL in clothes. Never had a leak and don't have to worry about staying on my side while sleeping. Can't recommend enough!
