## Questions & Answers

**Q: What is the rn #?  i'm looking for rn # 87958.  printed as part of the tagless label in the back of the garment.**
A: No clue but these have no tags

**Q: Are these ok for someone with thicker muscular thighs?**
A: Definitely size up. I have thicker legs and rear and normally wear a medium (33 waist) and I went with Large size and they fit perfectly. There is no way a medium would fit me. That size would be too tight.

**Q: What waste size is large**
A: It fits 32-38 comfortably

**Q: What is the fly pouch? Is it the same thing as the ball pouch? Im looking for the boxers with the pouch for everything**
A: No, there is no pouch
