I am 6' and 180 and the XL was too long so I returned it and went with the large which fits great. I would go with the medium or maybe even the small for your son since it seems like they are long in the arms and torso.

The medium sock should fit him well. My son wears a 12/12.5 and wears large.

I,m 5' 10'' and 210 lbs. I bought the XL which I find to be rather large on me. Being taller, the XL should fit you just right.

My son is 5'9 and about 130 lbs. It fits him very well (not tight at all). Just try not to dry it in the dryer. Hang dry is best. He loves it. Hope this helps.

I'm 6'1" 175lbs and a medium works for me. I believe it should work for your son.

I bought this for my 17 year old son who was about 5' 6" and weighs about 120 lb. He wears a size 18 or 20 shirt or small men's jacket. I guess it depends on how big your 10-12 year is.

I believe I ordered a medium and it fit fine. He is about the same size as yours.

My daughter was 50" and 56lbs when i bought them and got her a medium. They fit perfect. I would say a medium would work fine for your son.

I ordered MEDIUM for my son. But he was 5'4" and lighter (110lb )at that time. He is now 5'7" and they still fit.

The wet suit belongs to my son. He is about 6' 1" and probably weighs around 150 - 155. The size he got was MT which I assume is a medium tall. He is happy with the fit.

I am 6' and 170 lbs. The XL fits me perfectly. I would go with the medium especially if you ever want to put a layer underneath.

My regular pant size is 30x30, in 5'6; I would suggest a medium size for your son.

I'm 5'8" and I got a small 2", it's a little bigger than regular small. You might consider. Even though I don't like big clothes, he might fit in a regular medium, all depend on how he likes to wear his clothes.
