This is the second item we have purchased and enjoyed from Coolibar. The first swim shirt lasted our daughter 3 summers til she outgrew it. Now a friends daughter is using it. Still looks like new !!! This is constant swimming outdoors in Arizona......lots of sun and pool chemicals. A different brand much less expensive we purchased and tried and it stretched out of shape and wore out before the first summer was over. We will ALWAYS buy from Coolibar from now on.
