This cycling vest is great for layering. It will cut the wind on your chest. The tall collar is great for pulling up over your mouth and nose. Or you can leave it unzipped a little and not cover your face. Choices! The zipper moves smoothly along the entire vertical length of the vest. The vest has a double zipper, so you can pull up or down to change the zip-status. And there is a nice ribbon attached to the top zipper for quick and easy grabbing. The bottom of the vest is elastic. The chest of the vest is black, with red accents along the sides and the collar. The back is mesh keep the breeze flowing. While the tag indicates 6XL, I suspect the size is closer to 2XL. Armpit to armpit is 26.5 inches. Collar to hem is 25 inches.
