We spend a ton of time during the summer playing at the lake and in the sprinkler in the yard. One thing that has made the summers a lot more pleasant for my kids is the rash guards that I have gotten them. No more slathering sun screen all over them every day. With the rash guard I just have to do the remaining exposed areas. They no longer get burns on those little places that I accidentally miss with sun screen.
My kids have two kinds. My daughter has this full two piece from Mini Boden (on the left):

And both my son and daughter have a bunch from Old Navy.
Not only have these rash guards saved us time, but I have also save a lot of money on sun screen!
