My grandson is 9 years old his arm is thin &amp; his bicep isn't very big. What size should I get?

My son is 11 and weighs about 92 lbs. I ordered him xs/s. Even if you order the smallest size, it might be too big for your grandson.

Sorry for getting back so late. My son is 7 and is thin as well. The equipment all fit well and right as well.

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

I would buy the small size, my grandson is 13 and mine, which is a medium, is big for him.

Hi. I agree a small would work, but only if your son likes a very snug fit. A medium would work if he likes a little more room, but still snug. If in doubt have him try on one at your local sporting goods store. Oddly enough, my 17 year old softball player daughter who's 5'7" prefers a Large. It fits snug under her jerseys but allows for more movement so she's not choking.

Well, I got it to fit around my thigh like a garter, so if his head's that big he'll be alright. Or you could adjust it all the way down to bicep size and tie off the slack. I think your best bet would be just to buy it and let him be excited about one day being big enough to wear it outside, if he's not already. This headlamp is tough enough for a 6 year-old.

The sleeves are sized based on arm length more so than than circumference. Measure your arm from shoulder to wrist with a 90 degree bend at the elbow. The Pearl Isumi website recommends XS for a 23.5" length & 12" bicep. They recommend S for 24" length & 12.5" bicep. They're very stretchy so if your bicep is smaller, they should still work. If your arm is shorter than 23.5 the XS should still be ok. Mine are a tad long & have to bunch up a little but it doesn't bother me at all. Hope this helps!

I think small one is good for him. My son is 1,5 years old and I bought him both small and bigger ones. Big ones are too big, small ones are really good and I think will fit for a long time.

If your child has larger arms they should fit them. My nephew wears them, they do fit loosely on his skinny 9 year old arms.

I would say a small becouse, I'm 18 and the medium fits me but my hands are probably smaller than the average 18 year old. So I'm assuming a small would do for him.

I might try the medium first. I'm 13.5" around biceps and its baggy on elbows to wrist area. Pretty stretchy/clingy material.

I'm about 6'3" and 170lbs. I know this is like a year late, but if he's got lanky arms like I do, a Medium-Long would fit best.

I bought S/M size and have 11 inch bicep. It fits and is not to restrictive. So my guess is, small will fit. After use they will stretch also a little.

My guy is about 14lbs., 24 inches and he fits fine in the small (12-18lbs). He too is lean and long. His hands and feet are just starting to stick out. It's not as snug as a swaddle but has room for it when he gets bigger. For now, he's content with the size and has slept better since (about 5-6 hour stretches). I got both to compare side by side and returned one that didn't fit.

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.

A three should still be ok... these give lots of space in the arms anyways... it's more dependent on the length of their arms than the size and bulk... if you want to be safe go ahead and get a 4... you can always adjust the size backwards if it's slightly too big

I bought a size 4 for my 9 year old grandson on his birthday last year. He is normal height for his age.
