One of the most common questions we get here at Caveman Evolution is "what size knee sleeves should i buy"?  After selling 1,000s of knee sleeves we wanted to provide you more information so you can accurately size the best knee sleeves for you.

How to measure for knee sleeves:

Tools needed:

- Flexible ruler or printerable  paper ruler

1.)  Start by measuring 5 and 7/8 inches or 15 cm down from the middle of your knee cap.   Its recommended that you keep your leg at about a 30 degree.  We recommend that you stand while measuring for your knee sleeves.   If you don't have a flexible ruler available feel free to print out the paper ruler here -->  Paper Ruler PDF.  This will allow you to measure your legs.  Print in US Letter format.

2.)  From the 15 cm or 5 and 7/8 inch position, measure the circumference of your leg with a rule or the paper rule that you printed out..

3.)  Use the circumference measurement and reference it with the knee sizing charts below. 

If your looking to wear the knee sleeves during metcon style workouts then we would suggest sticking with the size chart recommendations.  If your looking for a competition fit/power lifting fit we would recommend going down one size so the sleeves are tight.
