My son is at 40 pounds and will be 4 yrs old soon wearing a 4/5T. What would be the right size for him?

My son is 6 and between 40-50 pounds and wears 7-8 in clothes. He needs the length in the clothes but is really thin and has to have adjustable waist. I bought a size 8 for the suit and it is a little long for him and plenty of room weight wise. But with the sealed neck and zipper ankles it works perfect and well worth the money. A size bigger than his normal clothes worked best for us.

I would suggest a small, my son is about 41 lbs and the uniform was a perfect fit!

My son is four years old and height 41.85, I got the Batman Muscle Chest Child Costume on size small and it was perfect for him. I ordered the size medium which is for ages 6/7 because I don't like him to use tight clothes and it was to big for him. I think the medium size will be good enough for your son or try the large size, it will be a little bit big but it will be ok.

My son is 130 lbs and 5'9" and his "small" fit him perfectly. My husband is about your size and for him I would definitely buy the large. By the way, this is a GREAT product! You won't be sorry. Helps so much!

Typically a size 4-6 fits a 4 to 6 year old. My nephew wore that size when he was 5 and it was a bit big.

I would get the medium or large. My son is 6 and 40 pounds and he loved the large (though it has plenty of room to grow into)

consider adult sizing instead. my kid is 3.7, weighs 40 and fit nicely to a size 4.

I would guess a size 3 would work well but buying a 3 and/or 4 and trying it is the best way to find out, and return the one you don't take of keep them both if the 3 fits and you have the 4 for when he grows into it. Otherwise return both, but the other answers are correct to look at the O'Neill site and make sure the height is right. If it is too loose it will let cold water in and circulate, if it is too tight it will be very painful and useless. It is a great wetsuit for the toddlers, best I ever saw. BD

Best way would be to measure him and compare to sizing chart. Our son's fit was true to size.

My son is 26 1/2 inches and weighs ~16 lbs and he wears the 6-9 month size. I think you want the 6-9 month size for your son, based on his height.

My daughter is 40 inches. The small fits my daughter exactly with no room to grow. Thus I think you might want to consider the medium.

I bought my son this jersey and he is 8. We got him a medium and he has room to grow. I would definitely say a large would be perfect for your son!

This is the perfect size for him. The weight limit is 106 lbs. My kids fight over ours because I got my son (5 yr @ 40lbs) this one and my daughter (8 yr @ 54lbs) the next size up (which I wish I wouldn't have) because his fits the both of them just right.

I would say Medium or Large. My son wears LG and is 26lbs and 35" and there is plenty of room for growth, but not too big.

Probably XL. I'm a 34/36. I have M and L. The M fit perfect. The L would probably go to 38, but I'm not sure about 40. Good luck.
