I typically buy 100% cotton sheets because I have multiple dogs and the hair doesn't really stick to the cotton sheets as opposed to other fabrics. Although these sheets are microfiber, which typically doesn't fare well with pet hair, these are a high quality with very closely woven threads that feel comparable to cotton. I am able to brush the hair off with my hand and most of it comes right off and doesn't stick. I love the sheets, they feel great, wash really well and plan to buy a couple more sets.
