Comfortable, just don’t believe the description

Yes, I recommend this

They are comfortable and soft, but cotton rich? Not so much. The label on them clearly shows they are made of at least 88% polyester. I have owned these previously where they are cotton rich, so this seems to be a classic case of using a cheaper material to cut costs but charge the same price. Not any fault of M&S, but I would suggest someone change the description on the website.

Comfortable & Soft!

Yes, I recommend this

I’m told these are super comfortable. After washing a few times noticed the khaki pair are slightly piling.
