What is the Calvin Klein Seamless Thong made of?

It is a modal and elastic string construction. The modal gives a soft, smooth feel; the elastic forms the waist.

Is it good under slim trousers?

Yes. The seamless build and minimal back keep lines flat under slim trousers and athletic shorts.

The modal blend is softer and smoother than basic cotton, but it needs gentler washing and costs more than plain multipacks.

Calvin Klein men's underwear generally runs true to size. The elastic string waist gives some stretch.

Wash cool and skip the dryer to protect the modal and the elastic waist.
