These are new underwear made by the Kirkland Signature brand to offer maximum absorption during your time of the month. I think the idea is great - an underwear that provides full protection in your sleep. It's super comfortable as it wraps you up nicely. & It has a dri-fit system so that it is constantly wicking away moisture and helping you feel clean and dry ! The biggest problem for me is the size & fit. Even though I got a small, I felt it was WAAAAY too big and very bulky - so in a way, that took away from the comfort.
