I have about 8 of these tops - short and long sleeve both, in various colors. I started wearing them several years ago and wear them 7 days a week - I have yet to wear one out or need to throw one away, they are awesome!!  The only drawback - the ONLY one, is the knit is a little heavy for Southern summer heat. But I wear them anyway, because the pockets allow me to carry my cell phone, keys, etc. with me. These tops are SO comfortable, and they wash and wear like a dream!
