## Questions & Answers

**Q: Do you have size chart?**
A: These come in different sizes, you must measure yourself and buy by following the sizing chart. The 3rrd photo at the top of the page is the chart. If there is not a chart, or you are being told these are one size fits all, do not buy, that's not correct.

**Q: Can I use it to practice mountain biking?**
A: It is light and does not bother the knees

**Q: Are these light enough to wear under the regular jeans ?**
A: I wear them over slim pant legs, and have worn them beneath snowboard pants which are loose fitting. These knee pads are slimmer than many others though.

**Q: Is this for one, or a pair?**
A: This is a pair, right and left, one each.
