At ten years old it all depends on how big your son is, is he over 4ft tall, and under 100lbs, then a med would be good for him, it should last for a couple yrs too.

My boy got these when he was 9 years old and it still fits him perfectly. He's smaller in stature and so are his hands. They are the size of a youth small but smaller than normal. Hope that helps!

mine are really nice! I ordered a size 10 shoe and got a size ten shoe. Your son will like them a lot.

Boys size 10 would be a medium. Medium is a 10/12. Large would be a 14/16. And this vest is really "way cool", to quote our young Indiana Jones..;~) It is cut on a slightly larger scale which allows for unrestricted movement in our young adventurer. I'd do this again in a heartbeat..! I'm really happy with this purchase..!Kevin..;~)

I think you will be good. When I bought them my son was A size 10-11 and he does good with them. They are a little big however you can adjust the tightness with the latches. We also bought these because all the other ones in his normal show size was way too small and could not even get his foot in them. We really like these especially since it comes with all the protective gear.

Hi I purchased a medium for my daughter she is 11 but very small so she where's about 8-9 pants and 10 shirt. The jacket is a little large but I wanted it that way as the sleeves are banded so you can pull them in. As I want her to get a bit of wear out of it. I would say the jacket would be more a 10 fitting. If your child is an 8 are they big or small? Do you want growing room? I love the jacket it was just what I wanted, I purchased the Large for my son and he wears a 12 pant and 12-14 shirt the jacket also has just enough growing room. I hope I have helped you with your sizing&#128522;

Hi JeffI purchased Lg for my son he is about a regular size 12 the jacket is a little large for growing room so Lg is a bit bigger than 12 say size 14. I purchased a medium for my daughter who is small and I would say it is around a 12. So if your boy is a standard 6 then if you want some room to grow I would guess small is 10 xs 8 and xxs 6. The jackets fit at the wrists so it is ok to have them a bit big unless you really need a tight fitting jacket.I hope that helps, I am guessing on size based on what I purchased, I thought there was a size chart, maybe try and look the jacket up on another website and see if they give you a chart to be more exact with sizing.

this summer I bought two O'Neil Youth Reactor full suits for my two kids. My son is 11 and my daughter is 9. I bought a size 10 for my 9 year old (which is small/petite for her age group). The suit was big on her (she normally wears a year behind her age) but the suit still fit ok. I expect next summer it'll fit closer to perfect. My 11 year old son is average to large and his 12 fit him pretty well. I expect he'll use it next summer as well, but after that will likely need another. I'd suggest buying the 8 for your daughter. Too small and the suit is useless. Even thought my daughters suit was loose, it didn't bother her at all, and she was thrilled to have the full after freezing in an ill-fitting shorty. this summer I bought two O'Neil Youth Reactor full suits for my two kids.

As per size matrix from http://www.meistermma.com/index.php?main_page=product_info&cPath;=39_41&products;_id=320, the size for your son is "M", i.e. 12.5"-15.5. Myself, I'm 15.6 and I'm stil wearing M, so your son should be fine.

Be careful when you purchase them. I didn't see an option for sizes. Large was way too big for my daughter who is 20. I believesmall would be best for a10 year old but you should ask the manufacturer. I felt like we got "ripped off"

The sizing is approximately European. I say approximately, because I can't find a shoe sizing chart that exactly fits the different sizings they say go together. My son wears a size 7 in American men's, and the ones I ordered fit him fine. I don't see the size I purchased or your size in their selection, so it may be sold out.

Go with a medium. I have bought them for both my sons at that age. They are average size boys. Small was very tight and uncomfortable.

I would think you would still be a medium. My son is 10 and the medium fits him fine.

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 8 years old & wears a size 7-8, it fit fine. My son is tall, the pants were a little short. No problem, I just made sure he wore black socks.

My son is 9 and a pretty big boy...I would say size wise its a 10-12. Hope this helps!
