The switchback is definitely a thicker wool than the shaks. Is this what your full zip looks like?- this is a switchback persimmon full zip:

Natasha- If sandra cancelled her order this morning, her medium might not show up in their inventory until tomorrow or so- changes take a day or two to process sometimes.
