Used Smartwool full zip hoodie, unsure of the exact model. Might be an older Merino 250 Sport Pattern Hoodie. Heather grey color with black accents in polyester. Merino wool (majority) with polyester (shoulders, pockets). There is merino lining on the inside where the polyester is so no poly touches the skin. Mens size small. Measures around 19" pit-to-pit. Does not have much stretch around chest/shoulders due to the polyester in those areas. Two zippered pockets. A nice feature is the hood is separate from the collar, so you can have the zipper all the way up and easily take the hood on and off. Good condition - no flaws, plenty of life left!
