Looking for some recs for period underwear!

I've been shopping around for awhile now and need some help in making a decision on the best period underwear out there. I noticed that a lot of the popular brands (Knix. Saalt, etc.) have their gussets (top layer) made from 100% polyester which I'm confused by since I thought cotton was the way to go.

Right now I'm looking at period company and maybe modibodi.

Would love any recommendations on these or any other brands.

Ideally I'm looking for ones that are waistband to waistband with at least the top layer to be made from cotton or similar material. I understand the absorbency layers would probably be polyester or something. I would also prefer a wider gusset to prevent leakage on the sides.
