The Women's Mia Flannel LS is a great Marmot performance piece. With technical hollowcore flannel, the Mia is a mid-weight top with increased thermal properties. This Marmot flannel is perfect for a late fall hike, with UPF 50, and its quick-drying and wicking woven fabric. With durable flat-locked seams, and double chest pockets, the Mia Flannel can be a staple for a long backpacking trip, or to keep you warm for those final fall campfires. Marmot's Women's Mia Flannel LS would be a prefect addition to the winter wardrobe.
