Patent for Long Sleeve 【Patent No. 7418058】
This patent pertains to the so-called Infinity Line. An overview is as follows:
The areas of fabric attached in a crisscross pattern are less stretchable compared to the main fabric, which pushes the shoulders back, thus promoting a corrected posture. This action applies resistance to the muscles in the back, making it effective for muscle strengthening through movements performed from this corrected posture.
Patent for Long Tights 【Pending】
This mainly pertains to the Infinity Line on the thigh area. An overview is as follows:
The fabric is applied in a band shape from the lower thigh (above the knee) to the back of the thigh (hamstring area) and also as a belt-like shape around the abdomen. This design helps prevent a backward-leaning posture, promotes correct posture, and enhances muscle strengthening through movement from this ideal posture.
