Under Armour Men's Bottoms Size and Fit Guide

WAIST: Measure around your natural waistline—right above your hips. Be careful not to squeeze too tight to allow a little give.

HIPS: With your feet together, measure around the fullest part of your hips to ensure you’ll have enough room to move comfortably.
