Dissident Gym Wear Aria Leggings are very comfortable. The fabric moves with your body and is stylish. The mesh is sexy with conservative coverage. They are marketed as compression pants, but the only compression factor I felt was gently around the abdominal cavity. The material is nylon and spandex, and I recommend these leggings to those with polyester sensitivities. Although I prefer shorts for leg days, squats were not a problem in the Dissident Gym Wear Aria Leggings.
