Using a flexible knit material with excellent elasticity and a pattern design/specifications that reduce clothing pressure, the feeling of tightness from the thighs to the knees is eliminated, relieving stress during movements such as spreading or bending the legs. Furthermore, the use of mesh on the back waist prevents the waist from slipping down when squatting. Comes with a loop for attaching keys or other items to store in the pocket.
