Review on UPF 50+ Swim Trunks for Kids - SwimZip Euro Shorties Available in Various Colors by Tim Airy

Bought for grandchildren, fits perfectly. He is large/large 3 year old and was concerned about the fit but that is spot on. I measured his waist and decided to go for it. I am considering buying a second one in the next size up as he is going through a growth spurt. The fabric is soft, stretches a little so lends itself to movement (and that's a lot) and washes well. He doesn't have the problems of rashes on his legs and thighs like many other costumes from his constant jumping. I highly recommend this suit.
