The ExOfficio Women's Storm Logic Vest is ready for adventure, weather or not. It features Primaloft Sport, which stays warm even if it gets wet, and is treated with a DWR (Durable Water repellent). Flattering stitch lines provide style and durability. The award-winning Storm Logic not only keeps you cozy in bad weather, it transforms into an adjustable travel pillow using the built-in stuff sack. A microfleece-lined collar and pockets, soft ripstop shell, and an interior Travel Pocket System all have your comfort in mind.
