The Chrome Warm Vest is not only warm, it gives you plenty of options when deciding when to wear it or what to wear it with. Whether you wear it alone or layered underneath other jackets, you'll be set. It's made with ripstop nylon with a water resistant shell and poly fill insulation which provides warmth even when it's wet. The Warm Vest is also reversible, so you can wear the rust orange side while riding and be seen then switch to the black diamond quilting side when you get to work for a more understated look. Or, if you want to take it off completely after you ride, it packs easily into the rear utility pocket. For a vest with all the features you think you might need, you won't be disappointed with the Chrome Warm Vest.
