I've tried a whole bunch of scarves (black or lavender colored), Bamboo vs Pashmina (don't know material, no such thing as "100% pashmina", pashmina is 100% cashmere handcombed from goat so NEVER less than $50+, but at this price I'm NOT expecting real).  Hands down, bamboo is softer & finer weave (the finer the weave the less the pulling) and Doesn't Pill over time (unlike acrylic, terrible).  All pashminas were still soft but not as soft as bamboo & coarser weave.  I've only given the pashmina as gift so don't know how it "wears" over time. Here's the final results, from best down in my opinion:
