What Our Gearhead(R) Experts Are Saying:"The Filson Insulated Wool Work Vest is the kind of piece that looks better the more you wear it. The wool exterior holds warmth naturally and takes on character over time, and the dropped back hem gives it more coverage than most vests bother with. It layers cleanly over a flannel for cold morning hikes or weekend work around the property."Filson's Insulated Wool Work Vest is patterned after vests from the brand's archive - a silhouette that earned its reputation doing real work in cold weather and hasn't needed much improving since. The 12-ounce wool and nylon blend exterior holds warmth naturally and resists the kind of daily wear that breaks down lighter fabrics, while 60g polyester insulation adds a layer of synthetic warmth that keeps performing through damp conditions. The dropped-back design extends coverage below the waist, where most vests fall short, and the rib-knit collar seals warmth in at the neck. It layers well over a heavy flannel or midweight base for cold trail days, and wears just as naturally on the drive to the trailhead or a weekend in the mountains.
