Only 60% cotton, it is not mentioned in description

These are listed as "Men's Cotton Classics..." What I received were compose of 60% cotton, 40% polyester. Very different material, and not something that I would wear, especially down there. I have returned them and I'm still waiting for my refund.

Very comfy, well made and very soft rubber band, also good fabric breathable fabric.

It say it has button fly but it does not. I'm returning it.

[This review was collected as part of a promotion.] I bought these boxers to use as pajamas. I understand that they are a cotton blend, but I've had blends that were soft and comfortable. I expected better quality from Calvin Klein. These are pretty rough against the skin and not very comfortable.

Description of fabric is incorrect. It is only 60% cotton. The remaining 40% is polyester. They feel thin and scratchy. I will be returning.

High Quality fabric smooth like bed sheets. Feels like sleeping commando in bed! Leg vent gives freedom of movement without too much fabric to bunch up. Best boxers out there.
