I'd like to amend my review from 3/25/19, because my opinions about this vest have changed dramatically since I've been able to use it. I have commuted to work every day for the month of April, and this vest has accompanied me on most of those trips. First and foremost, I am happy to report that the zipper problem I was having has completely disappeared. Perhaps it just needed a little breaking it, I'm not really sure, but it functions perfectly now. Additionally, since it's a 2-way zipper, it vents from the bottom up, as well as from the top down. This is a nice feature, and one that is not present on any other cycling apparel I have. This vest has been perfect for temperatures in the 50-70 degree range. I have much preferred adding arm warmers to this vest for colder temps and thereby avoided having to wear a full jacket. The back full venting, without pockets works well for me because I'm usually wearing a backpack or messenger style bag when riding around town. Also I like the solid black colorway and stealthy appearance because you can easily ride this vest to work, church, restaurants, or just around town without looking like a cycling superhero. I've found this vest to be a super addition to my urban cycling kit. Great job Chrome and Dustin.
