Tips to choose the right size:
- Tighten the tape around the wider part of your hips.
- If your hip measurement falls in between 2 sizes, choose according to your preferences: a larger size for a loser fit, or a smaller size for a tighter fit.
- If your height measurement is 1 size bigger or smaller than the hip size, we suggest you select the size based on the hip measurement only.
- If your height measurement is 2 or more sizes bigger than the hip size, we suggest you select one size in between.
* If you cannot find your size on this table - you are a smaller or bigger size than the ones showed on our size guide table, please contact us at: info@mude-sports.com
