Warm Filson Polar Fleece vest. No size tag anymore, but fits like all the other Filson mediums I own, maybe a little bit on the larger side. I'm 5'10" 180lbs and it fits roomy and appropriate. Zipper closed side pockets (useful and safe) and one internal zipper closed pocket along with two open inside pockets, but due to where Filson sewed the attachment for the outer pocket zipper clasp the inner pockets are pinned closed for 1 cm in their middle...still useful. Strong zipper and healthy elastic on bottom cuff. Great layering piece for under a tin cloth cruiser or similar.
