The SF Phalanx Fleece is a mid-layer designed to provide essential warmth for layering up in mid-low temperature environments. The body’s natural warmth is contained in thermal air pockets constructed from precision knit, napped, and sheared polyester. HIGHLOFT™ consists of hydrophobic yarns that repel moisture and speed dry times. This symmetrical design is not only soft, but also reduces surface friction for versatile layering options. External hand and chest pockets provide stowage for mission essential items. Phalanx formation – prepare to ADVANCE!
