This brand-new baselayer from The North Face utilizes Merino wool integrat- ed with a wrapped (i.e fibers arranged in parallel orientation) filament yarn that allows for incredible stretch without the weight and moisture retention that elastane has. A raglan design—meaning the sleeve extends in one piece from the collarbone—allows for a more natural movement and the aforementioned Merino wool ensures you remain warm and don’t stink up the joint, either.
