Exact fiber content is 86% Bamboo, 12% Acrylic, 2% Polyester, which sorts out to the structure aspects of the yarn (shown above). So, the bamboo would be that fuzz on the right, with the acrylic on the left and the polyester in the middle. The acrylic serves as the core of the yarn, with the bamboo 'core spun' around it. Then the polyester thread is laid down as a binder and shaper on the outside.

Additional features of this yarn include a certification by the Forest Stewardship Council (www.fsc.org, cert. no. SW-COC-002192) stating the materials come from "mixed sources [of] ...well-managed forests, controlled sources and recycled wood or fiber." This adds to the appeal of the texture with a bit of 'good for the environment' karma.
The cheapest source I've found for this yarn is AC Moore, where I recently got it on a 25% off sale at $3 per ball. This is good since you'll need 6 balls for the scarf... Most internet sources I've seen are selling it at $5 per ball. If you see something better, please leave a comment!
