Keeping the core warm and dry is key to staying comfortable as the temperature drops. Filson's Tin Cloth Primaloft Vest is built to do precisely that. The shell is made from a tightly woven canvas treated with liquefied wax under high heat and pressure for lasting water resistance. Underneath is a layer of PrimaLoft Gold insulation, a lightweight synthetic that mimics the heat-holding properties of goose down while retaining 98% of warmth even when soaking wet. Fleece lines the collar and zippered chest and handwarmer pockets, an interior pocket on the right chest provides discreet storage, and a cinched hem offers added protection against the wind.
