“The instructions say to get a size up and we did and it's fine, but when I say runs true to size I'm assuming you are doing that too. We got a tee for each male in the family (the ladies already having theirs) in different colors so everyone knows which is theirs. We wash all the Insect Shield clothes together and our previous ones did seem to last as long as they say. All of the tees we got are marked both inside at the neck (print, nothing scratchy) and with the green cross logo outside on one sleeve at the edge so you can't forget which ones are your Insect Shield ones.”
