It was knitted with a little more than 400g of Cascade Sierra, 100g skeins, color 50, lot 8028. Unfortunately it is discontinued but although it had only about 20% wool in it, it gave the Pima cotton enough springiness in the yarn. I made it with elbow length sleeves.
Although it is mid October here where I live (and I just WISH it would cool down) the yarn was infinitely comfortable and breathable, despite the unseasonable warmth at the moment.
