So ive been hunting for quite a while now for 100% opaque leggings. After holding many a pair up to the light and finding them quite see through, i went to Athleta-based on the quality recommendation post. Hurrah, i have seen the light, well no light thats why i bought them I havent tried them out in the gym yet but if they stand up to all my dancing, kickboxing, barre, pilates, yoga, etc im a convert. Theyre definitely spendy, but i decided its worth it since they work so hard.
