We love the feel of soft and cozy men's fleece jackets and sweaters when the temperatures start to dip. A layering essential on the trail or in the backyard, our eco-friendly fleeces are soft and durable and will quickly become your new clothing favorite. Designing a functional fleece layer starts with sourcing the best fabrics. At Royal Robbins, we like to use sustainable materials like pesticide-free hemp and certified organic cotton, which provide natural thermal performance, odor resistance, durability, and of course, softness; these materials are both easy to take care of and easier on the planet, making it an excellent choice for long-lasting outdoor clothing that will last for years to come. Merino wool is also an excellent fleece material that is used for its sweat-wicking performance and enhanced breathability. From quarter zip, to terry crew and hoodie sweatshirt styles, our fleeces provide the perfect lightweight layer for any adventure.
