These are the original Mossimo athletic fit t-shirts like before Target ruined the original design catering to the general Target shopper’s body type.They’re not cotton, but do have a soft feel.Mossimo designed these shirts for us who have larger, broader shoulders, a narrower mid-section, and a more athletic build.If you don’t have an athletic build or you have a big stomach, these are probably not for you, though they do stretch some because of a some spandex woven in.These have a more sleek feel and don’t have volumes of baggy loose fabric around the midsection like so many other t-shirts out there.The fabric is thinner which gives a great feel. I still have original Mossimo thin cotton t-shirts from 10+ years ago worn regularly and they are still holding up. We’ll see how these hold up.I’m thankful for Mossimo designing shirts that fit me.
