O'NEILLYouth Basic Skins UPF 50+ Short Sleeve Sun Shirt

Great thing about swim shirts is their UV protection, bad thing is they are meant to be fairly closely fitted - which my son doesn't particularly care for. However, this shirt seems to mostly fit the bill. Ordered a size 16, he is an average build 5' 4" 115lbs who wears size 16 in most clothing brands, those who are familiar with the Under Armour youth fitted clothes will notice the fit of this shirt is very similar. The sleeves and lower part of the shirt are close to the skin but still slightly loose as expected especially given the "slim fit" nature, the tightest part of the shirt for my son is right at the chest area - so maybe slight small but still manageable. Overall it is a great product.

I have owned several O'Neill rashguards and have been happy with durability and fit. The last two thinned in spots on the first few wears. Returned both. Don't know if they were old or damaged, but weren't what I expected.

Order one size up. I understand these shirts should be "snug". The issue is: the shirt must actually FIT. The sizing is wrong, as I suspected. My son is slim and small for his age, but growing. I ordered a size larger than what he wears, thinking it would be ok if the shirt was too large, since this summer he will probably grow into a bigger size. I am glad I did, as the shirt would have actually been too small if I had ordered his current "correct" size. It fits him now, with no room to grow. I will keep it, but he won't get a lot of wear from it.

I wanted to buy my son, who is about to turn 12, a newer and bigger rash guard. He’s average height and slim build. Maybe 80 lbs. the material felt nice and stretchy, like it would be comfortable. the neckline didn’t seem suffocating like a lot of rash guards are. I ordered neon green size 14 hoping he would have room to grow. It was VERY short...so I exchanged for a white sized 16...essentially fit exactly like the 14, they run extremely short.I added photo comparisons from my sons current rash guard that runs a little longer, white sharks sized M (8), and also a grey adidas performance shirt size L (10). As you can see, these O’neill rash guards run very short. But it was not too tight in width, only length. I’m surprised that other reviews did not mentioned how short these run. The quality was nice, I wish they had fit.

I bought this for 10 year old. It is very well made and thicker than others but i presume that is the UV protection. It is good since he is slim and will insulate from the cold waters. It is slim fit which is fine since he is slim but if you son is huskier then choose one (1) size larger.

My son won't go swimming with out a rash guard. I guess he feels too modest or something, which is bizarre because he is not fat at all, he's a skinny twelve year old. He is about average in height for his age and kids he goes to school with, I bought the size 14 because he also wants his rash guard to not fit tight like they are meant to. Well this fits just as he wants, it's slightly loose on an average sized twelve year old but certainly not too loose for swimming, I imagine it would fit perfectly as in snug but not constricting at all on a 14 year old, you know the way rash guards are intended to fit. Anyhow we are both happy with the purchase so it's a win win.

My kids are fair-skinned and burn easily. A rash guard is a must in the summer for UV protection. This product is tailored-fitting but not tight. It's just right, looks good, and washes well. Recommend.

As far as swim shirts go this one does what it’s supposed to do. The fit was great, which I wasn’t sure about. My son’s only complaint is that the material is very thin and it clung to him the moment it got wet. I’ve purchased other swim shirts that were thicker and retained their shape/fit a lot better when wet. That was the only issue, otherwise it was a good purchase. The color matched his swim trunks perfectly.

Great fit, easy to get on and off. True to size. My son loves it!
