## Questions & Answers

**Q: My son is 14 years weight 100 pounds what is his size**
A: He'd be between a L and XL, depending on waist size. I'd say L for an average build, XL if waist is larger build. 100 pounds at 14 sounds closer to L though. Hope this helps.

**Q: What size is the  xlarge youth**
A: I would say size 16. My son wears XL in Nike pants, size 16 dress pants, and wears YXL underwear. Hope this helps!

**Q: my grandson wears a size 6 so what size underwear will that be...s,m, l???**
A: Hi,
It depends... is he skinny or husky? According to the Under Armour chart, he’d be an XS, but if he’s on the huskier side, get small.

**Q: Do these have cup pocket?**
A: It does not have a cup pocket.
