Question: My grandson is 9 years old his arm is thin & his bicep isn't very big.  What size should I get?
Document: Bought this for my 9 year old and he absolutely loves it! He had a youth arm sleeve from the NBA store and the top part was way too big so we had to keep safety pinning it, but this one has the elastic and fits perfectly. Might get him more!
This sleeve fit perfectly for my 9 year old son. It does its job and keeps his arm warm. We would order this product again and it shipped fast.
Ordered this for my son. He is 12years old. I ordered him the small and it was the right size. He is an average size boy. He likes it.
Ordered this sleeve for my 10 year old son(who had broken his elbow) for basketball. After trying other sleeves, I finally found the right fit in this sleeve. It was the only one that didn't fall down while he was playing basketball. I ordered the small size to begin with and it was too small so I exchanged for the larger size. They were very fast in their exchange! Highly recommended this sleeve for your child.
I ordered this for my 12 year old son and it fits him well I've had a hard time trying to find a sleeve that fits him well for baseball and this sleeve did the job, it's easy to put on and take off and it's durability is very good the great thing is that you get 2sleeves as oppose to one at the store I would definitely recommend this sleeve to friends and family for their kids.
the Youth size fit my 8 (soon to be 9) average sized nephew with room to spare, but still snug enough for compression. At this point, the &#34;look&#34; is more important than functionality, but he absolutely loves them.
I bought EXXO arm sleeves for my 13 year old son for both soccer and lacrosse. He loves wearing just the sleeves to start off practices and games on chilly days. It is much easier for him to just slip off the sleeves then to take off any other type of under layer. The sleeves are very comfortable and fit perfectly.
This was for my nephew..... He was very anxious to receive it. He is a small 11 years old... My nephew said it was PERFECT!
These are great for my son, who uses them when he plays football and basketball. Easy to put on and off. He is skinny so we ordered the smallest size and they are perfect. I think his biceps are 13&#34; around, so keep that in mind if you order. Would order again in the future.
Bought these for my 9 year old who wanted to wear them with his jersey while playing football. They fit great and my son loves them.
