Made with plush polyester sherpa, the Men''s Aros Fleece provides delightfully soft warmth for those chilly fall hikes or nights around the campfire. The high-pile polyester sherpa provides a moisture-wicking and lightweight fit for comfort on active and laid-back days alike. As a plus, Marmot made this jacket with 100% recycled materials for an eco-friendly fit in a retro fleece style.
