Not sure what the fiber is but it feels like shetland or icelandic to me. Not soft like merino, but soft in a slightly rustic and wooly kind of way.
These two are not the same colorway, but they're close enough that I spun each and plied them together into a two ply:
I'm pleasantly surprised with the result. The yarn is maybe a dk or light worsted weight. I think I have enough yardage here for a nice shawl.
