From the website:

This is a general purpose yarn that I am sure you will enjoy.

We wanted to have a yarn that would be perfect for knitting fine dress sweaters. This is a very nice hand blending of fine merino, seacell, cashmere and bison. The yarn is very soft, strong and warm.

It is spun as a light sport weight at 200m/50g in a 2-ply and available in Ecru and unique hand blended colors. Pearl Bison is a pleasure to knit and I am sure you will love it for any fine project.

65% fine merino
20% Seacell
10% Cashmere
5% Bison
