Their vests are felt, about 1/2" thick and very warm-a great product. They aren't tight, but neither are they baggy, loose enough to wear a jacket under it (if the buyer has special needs, call them). The seams are well sewed and very sturdy. The collar is high and comes up high enough to cover your ears. Cleaning instructions per Chris: "You can clean your vest by soaking in mild vegetable based soap (i.e., Murphy's Oil soap)in a large basin, the dirt will draw out. You can agitate a little, but not vigorously, by hand, then let water run out and hang dry. Blot out any stains."
