Icebreaker Terra Long Sleeve Half Zip Hood Merino Wool Jacket Blue Small The perfect pull over 3/4 zip jacket by Icebreaker. It is a merino wool jacket, however the fabric content tag is cut out, so I am not 100% sure on the amount. The perfect base layer for skiing, hiking, camping, or casual wear. Has a hood and a mini arm pocket. There is some slight piling. It is pretty minimal, but I still wanted to mention it. See second to last photo.
