It looks like a nice rashguard but it's so small my son wouldn't even try it on. We would send it back but it's quite comfortable for his sister who is three sizes smaller.

It's so small! I ordered the size Large as it's my son's size that boys are supposed to be by the age of 12. This large fits my little nephew who is a size 6. The size is terrible.

I bought this for my son but it only lasted about a week before it stretched so much we had to replace it. Admittedly used every day by the pool and dried in the sun but still very disappointed with the quality.

Heavier material than I expected. Good quality. Runs a little shorter than I would like for my 8 year old average height. We haven't used much in the sun to know sun protection.

These rash guards are nicely made but a bit small. I ordered the small size (8) for my 4 almost 5 year old grandson. He usually wears size 6/7. The shirts fit perfectly. You can order the size in this.

Everything looked good at first, but after a week in the West the fabric stretched a lot. It went from a perfect fit almost to the knees.

The second shirt after the first stretched so much that it became unusable. The same happened with the second one with infrequent use.

I used the spreadsheet and restore to purchase the regular size. Turns out 1-2 sizes smaller than expected. My child is very slim and wears a size 14. I bought a size XL and it runs small.

I bought this for my son. He swims in a chlorinated pool or ocean about 4-6 days a week. The shirt gives my son great protection but as you can see from the photos it is wearing out. I need to replace it so my son has full protection. The shirt lasted less than 2 months. I bought this swim shirt for both men and boys and both were worn out.

These dimensions are wrong! I bought two of these for my boys who normally wear Lands End and Cat & Jack M&L boys rash guards with room to grow. They were incredibly tight. I give my youngest son a size L and am hoping that XL will become available for my eldest.

I have such a hard time finding long sleeve rash guards. It is wonderful! I will buy more. It was a bit small but my baby's head is a bit bigger so it could just be us.

Sizing does not match at all - does not match other Revain branded products. Size M/8 did not fit my typical 8 year old but was perfect for my 5 year old.

Bought this for a 4.5 year old and ordered an XS (luckily got it instead of a 5T) and it fits him. My son is not very tall and weighs about 43 pounds and size XS fits him. It was cut close enough to his body that it didn't ride up, but most importantly it offered excellent sun protection. He was in the sun from 10 a.m. to 6 p.m. and never complained that he felt unwell and had not burned himself. I would buy again but be careful with the size. UPDATE REVIEW: Bought 5 months ago and already used

As another user noted, this rashguard will only last through the summer if you take good care of it and don't use it every day - and even then, those days are numbered. I bought this rash guard for my son as we swam a lot over the summer and I have to say I am disappointed with the durability of this garment. He has last year's Body Glove Rashguard in comparison which we are rotating and the Body Glove Rashguard is still in great condition! It's just getting a little small for him since it's…

I bought it for my sons in early June. In the summer they swim once a day, and by the end of July these shirts were so worn that they were unusable. One was so stretched it was literally dangling off my son's shoulder. We never washed them in the washing machine, they were only used daily in the pool. My kids haven't done anything crazy to stretch them. They just lost their shape. In a way, the low price means I can't get too upset that I've been wearing them for almost two months. On the other
