When could you not use a soft wool zip-up hoody? We're pretty hard-pressed to think of any situation besides the opera or sumo wrestling. At any other time--i.e. a casual Saturday, a work day, a campus day, a date, a trip to the yoga studio, or an evening baking session--the I/O Bio Merino Women's Signature Pocket Hooded Sweater will keep you at just the right temperature. When you hit a hiking trail or practice your eagle pose, the wool breathes and keeps you dry. And as you wait for the ski shuttle on a chilly morning, you'll thank the stars for wool's insulating power.
