The North Face Women's Aries Hybrid 1/4 Zip is a new wool blended performance top that will promote superior breathability while providing natural anti-odor properties. The merino wool fibers are blended with polypropylene for increased stretch and faster dry times. This top also has 1/4 zip construction, a napoleon pocket, and thumb holes at the end of the sleeves to make layering much easier. Flat locked stitching reduces chaffing and this shirt also has a UPF 30 rating.
