Lightweight, warm trekking shirt with a generous, relaxed fit. Made of functional polyester flannel that insulates, wicks away moisture and dries quickly. The ideal shirt for hiking and general outdoor life either as a base layer or as a warm mid layer worn over under garments. Two chest pockets, one open and one zippered. Please note that this shirt has a relaxed, wide fit so the sizing is generous – select a size down if you prefer a regular fit.
