DEEP TOUCHWomens Seamless Underwear Boyshort Ladies Panties Nylon Panty Sleep Boxer Briefs 5 Pack

I purchased these and like them but am concerned that there is no cotton lining in the crotch. How do these keep you comfortable?

Is it cotton?

What is the inseam measurement?

Are these silky feeling or do they feel like nylon that csn snag dry skin on your hands?
