"Shark pants" are made of oxygen-resistant elastic yarn and nylon yarn. Perhaps speaking of these two fabrics, you will be unfamiliar and easy to understand. They are very close to the material of swimsuits.
"Shark pants" are characterized by hip lifting and contraction. It is much more elastic than leggings. It can hide the flesh of your hips and abdomen, create a small waist effect, and gather your hips together, which has a very good hip lifting effect. Moreover, "shark pants" are very docile, so don't worry about wrinkling like leggings, which will affect the appearance, and the leg lines are easy to outline because of their shaping effect.
