The Plose 5 fleece is a full-zip thermal midlayer made of wicking, packable 180-weight Polarlite Microwaffle, our proprietary fleece with a soft brushed inner face that traps heat. Built for simplicity and protection for alpine trekking and mountain activities, the ergonomically shaped sleeves and flat-lock seams allow good freedom of movement and the comfortable regular fit layers nicely beneath a shell. With a soft inner collar, snug elasticated cuffs and hem to keep the wind out and a slit zip pocket.
