Built For Your Itinerary, the FYI model men’s puffer vest is a hybrid layer with a horizontally quilted front for light warmth. Details stay purposeful: a two-way zipper, standing collar, side zipped pockets, and elastic trims at the armholes and hem. Cut in breathable, four-way stretch fabric that packs down fast, it’s the slip-on solution for trains, planes, and everything in between.
