My child is 13 and I'm not sure if he should be in the 'youth' sizes or a small men's. He is 5'1" and weighs 98 lbs. Any info would be appreciated.

My guess would be youth. I personally have a Large that fits well, and I'm 5'11 and 230lbs. Best of luck.

I think you would be able to get away with ordering a youth x large. They are usually cheaper in youth sizes and I think it would fit fine.

Do you mean 6.5 as a toddler or 6.5 as a teenager? If a toddler XS youth will be a little big, but kids grow fast. If a teenager, then get him Men's Medium. Hope this helps.

Its really all about weight. This is probably pretty close to allow for some growth. We bought the medium for our sons 11th birthday and he's about 80 lbs. the zap web site has some guidelines on sizing as well.

My son is 7 years old and is tall but thin. We ordered the small and it fits great with layers underneath. He may even be able to wear next season.

Your son is longer than my daughter (25 inches) but weighs the same. I think the length would force you to move to the next size quickly. I would probably go with the next size.

Given that I have only bought one size, and I am a fully grown adult, it's difficult for me to recommend which one you should pick for your son. But, I did scan through the reviews to see which ones mention buying smaller sizes for their children. I came across a few that would at least come close to your son's statistics. The first one I found was bought for a 9 year old who was "Very tall" for her age, and they got her a medium. The reviewer said that if you buy a size perhaps slightly bigger than you were hoping for, the outfit comes with several straps that wrap around the waist and legs that can tighten it. (which I can confirm is true.) The only part that I've ever found to be loose is the upper chest region. I can't even seem to get that region to stay tucked in when I move around too much in the outfit. Also, another reviewer bought this for her 13 year old son who was 5'7 and 120 pounds and chose large. She said it was "a tad loose, but not too long." This is probably the example you were looking for, so listen carefully: Given the fact that you son is the same age as hers, and is both shorter and weighs less than her son, Medium might be a wiser choice - but remember I can't confirm that, I've never bought or tried any other side except for XL. At any rate, I think whether you pick medium or large everything will be fine. The medium might fit perfectly, and the large, if you decided to get that one, would at least be really comfortable, nonrestrictive to motor functions, and more importantly; he'd be able to continue using it as he ages and grows. So either decision you make I think you'll find good things about either of them. Hope I was of help.

My son is 5' and thin. The size small is slightly large for him, but I wouldn't 't have ordered any other size.

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!

We got a size M for my 13 year old son who, at the time, was probably about 5'2. It was a little big but perfect for growing into and he has!

The sizes tend to run larger than normal. So if he wears a medium a small could fit. Large would be way to big. Keep in mind its to jump around in and you want it loose. Its an awesome product for the money.

I think the safety rating is the same, it's just sized smaller. A large youth size might not fit you, so check the fit/sizing info to be sure.

I think it might be to small. My son was 9 when he wore it and he was 4'3" and about 60lbs.

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.

If he is a larger kid then I would say this headgear would be fine, otherwise I would purchase a youth size if possible so that the head gear will have a more snug fit.

Medium is meant for 5"4 to 5"7 so medium is probably the best fit for him. I'm 16 and 5"11 yet I use medium because they're little and light and being the forward I want to be I think it's best but that's my opinion and one day it'll probably screw me over but yeah medium for a safe nice fit

I just seen the one that said size small and size youth med..... They just run really small my son that just turned 3 has the small size he was able to wear it last Halloween and will wear this Halloween then wont be able to wear it again the pants run small.ANd i think he's size said made to fit a 3-5 year old but no way is that true. My sons med wouldnt fit an 8 year old like it says. might fit a petite slender 7 year old. Makes a nice costume. My son was just excited to get a helmet so then i dontated the rest of the costume so someone else could have it instead of sending back.
