The 509 FZN Women'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 ¼ zip makes it easy to throw on or take off.
