So here is where our Southampton Sun Block UPF+50 Shirts really do the job - for our little ones who are so vunerable to Ultraviolets and sun burn these shirts will protect on the first day or if they got a burn without the shirt wearing it the day after it will offer complete protection and they can go out and about instead of having to stay home - The UPF+50 Youth Crossed Oars Long Sleeve making parenting a little bit easier - we're happy to do it!
