I didn't have a problem with these right away, but now that it's winter time and I'm having more skin sensitivities due to dryness, I find my skin gets irritated (itchy) after wearing these for awhile. Aside from these more recent symptoms, I have been very happy with the product. They do not show much, if at all, through T-shirt material, and they are easy to wash in time to be ready for the next day. They can be hand-washed quickly before bed and dry by morning. If you don't have any known skin sensitivities, I think you will really love these!
