Women's underwear 🩲 that covers the entire buttcheek

I feel your pain. Traditionally it just has to be the 3-packs of Hanes or jockey for 100% cotton (in hipster I think? briefs are super high waisted) Some of them have a very short lifespan. I would have to imagine that nowadays there are better or more types of 100% cotton underwear…but I haven’t really found any. I don’t understand how anyone can wear underwear that cuts across the middle of the butt cheek, madness!

I just bought a few pairs from this brand, Knickey, based out of NYC.

They are so comfy and meet all your criteria. Highly recommend.

Try the Gap, they have lots of options at reasonable prices

Calvin Klein is my favorite - you can find them sold in sets for pretty cheap at places like TJ Maxx and Marshall’s , Macy’s

Bonds Australia make great ordinary bum covering undies. I wear the hipster bikini style, but they have all the rises including super high (bonds cottontails) and period underwear.

I abhor boyleg undies because they give me wedgies and feel terrible.

I think what you're looking for is full briefs. Depends where mid rise is now classed as.

How about these?

I used to be able to get good seamless underwear at the Jockey outlet, but I haven’t been shopping in so long I’m not sure if they even still exist. The gap outlet online used to have full coverage underwear, but I can’t guarantee those ones are cotton. Or that they even still do underwear.

Not cotton, but seamless and covers the whole bum. Love them: https://a.co/d/1MJAOvp

ETA: these look like they might be really good https://culpritunderwear.com/womens/apparel/ladyboxers?id=6999705845818

If you're open to bamboo, I recommend Boody. My favorite is their Midi Brief & LYOLYTE Full Boyleg Brief.
