This will definitely work for you. My boy is 48in and about 44 pounds. And we spend a week in NY and that was all I used.

I would recommend a small. My son is 9 and 90lbs and the small fit him snug. We recently move up to a medium which provide more room.

Our son is 40 inches tall and 35 lbs and it fits him quite well (very sturdy too). I'd estimate it would be just fine for your grandson. In any event, hope that gives you something to go by.

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

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.

I haven't officially worn the hat yet, I've only put it on my head briefly when it first arrived. If my memory is correct, it felt a little big but would be OK to wear. I'm sure you're OK but i don't think it would work for your son. An option would be to wear a light weight knit hat under to help it fit him.....

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.

Our G'son is just recently 6 and is is 48 lbs. The shirt is little bit long & they fit on the tight side. We like the Medium.

I ordered a size large (12-14) for my son and he weighs 77 lbs and is 4'11-- the fit is great, room to grow but doesn't look too big. It's because he is so skinny. I think the med would have been too short in the sleeves. I like that he has room underneath to layer. He loves this coat! I think the large would be fine for your son- he would prob quickly grow out of the med as they seem to be close to the same size. He is slightly shorter but I don't think it would be too long. I hope this helps.

My six year old son fits fine, but he's pretty small. He's 43 inches tall and 45 lbs

My son is 45 lbs. and the Large size did not fit him, although they are supposed to fit 45 lbs - 60 lbs. so i returned the product

I'm 5'9 150 lbs and I got a small. I have enough room to move around comfortably. It really depends on how he wants it to fit. If he wants a bigger fit, go with the medium. If he wants something a little more fitting, go with the small. You can't go wrong with either.

I bought it for my 5 year old and it fit him he weighs about 42 lb. I would look for a medium.

My son is 7 and weighs around 50 pounds. He is very slender and tall and it just fits him. He will not be able to wear it after this summer, I imagine it will just be too tight at that point. I hope this helps.

It is a tight shirt but his regular size should fit him ok. Going an extra size never hurts.

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!
