Two long leggings made of swimsuit material. I usually wore these when it was cold, so I haven't used them in a pool. Therefore, there is no deterioration from chlorine, and they are in relatively good condition. I don't see any areas where the fabric is thin or worn. Waist (laid flat): approximately 31 cm Inseam: approximately 63 cm Made of nylon, they stretch well and are very comfortable to wear.
