I have sensory processing disorder (SPD), and I was devastated when the leggings I basically lived in last year got contaminated with mold and I had to throw them out, since I am really picky about how clothes feel.

So, enter these leggings. They are a little snug (I am 5'4" and 135 pounds and got a Large), but it's comfortable. The waist band can be a little snug but at least it's about 1" thick elastic so it doesn't dig into your body too much. The material is thick enough that it's warm in cold weather and not see-through.

Basically, some really solid, thick, durable leggings, compared to many others that are too flimsy or cold.
