Ok a couple things here that are important.  I received the wrong colors and based on other reviews, you should be prepared to do so too.  So if you want these color (which is why I ordered them in the first place) you'll have to deal with bright colors.  I am personally a fan of neutrals and I don't much understand why they don't sell a full package of black undies somewhere, anywhere (believe me I looked).  There are functional reasons for having black, for pre-menopausal women.  I hate bright colors, so I don't get the whole I want my rear end to look like a traffic cone or a electric neon sign on the Vegas strip.  To each her own.  Just be forwarned.

That being said.  Full cotton underwear are incredible and so much better for the body.  If there's an option, I'd go full cotton over anything else any day of the week.  Also, another nice thing about these undies is that unlike some elastic banded undies, the bands do not cut into the skin.  That is an exceptional touch.

Someone mentioned the legholes, that's why I marked these somewhat small.  I'm a couple sizes smaller than the ones I ordered, but I'm in a wheelchair so I order large for easier removal.  If I didn't need a couple sizes up, I can definitely see how those leg holes would be small as I'm a pear shape and have a bigger bottom than other proportions.  I wouldn't say it's a huge deal, but it could go snug.

One star review is for the colors.  If I'd seen that review (which I just noticed before), I would have never ordered them.  I ordered them on Amazon because I needed them asap, so not time for refund, but I'm not giving a 5 star review on a great product (it is a great product)  but it is the wrong product.
