They’re a bit bumpy, especially with the extra fabric on the sides, but maybe with some compression shorts or something they’d work under jeans. The padding itself is a bit on the thicker side so it might be harder to be discrete about, but the fabric itself is nice and soft so at least there’s no classic plastic crinkle.
I ordered a case of them not too long ago from Rearz and really loved the print and they were really comfortable, but as with most pull-ups they leave a lot to be desired in the absorbency category.
