The 509 FZN Women&39;s Merino Quarter Zip Shirt provides versatile midweight warmth with a Merino wool blend that is high performance and comfortable in all conditions. Naturally soft, breathable, fast-drying, and odor-repellent-all without the itch of conventional wool-this unique knit is far superior to conventional fabrics. Stretch properties add mobility and the cozy turtleneck 1/4 zip makes it easy to throw on or take off.
