The vest is perfect for cycling with the opening in the back to access my jersey pockets. The reflective metal material works amazingly. I can tell a significant difference between this vest, a previous versions of this vest that I own and competitors vest. I really notice how the reflective metal material returns my body heat about 2 miles into my warm up. Other vests don't exhibit this capability and it is very noticeable when they are worn. I also appreciate the side pockets this vest now has versus the previous version. I thought the side pockets would get in the way if anything was placed in them or would fall out. I find they are perfect for holding a pair of sunglasses at the start of a pre-dawn ride. The side pocket is also useful after having removed the vest and folding it into one of the pockets for storage in my jersey pockets.
Very packable. The front has heat reflecting and wind stopping fabric and the back is breathable. Runs true to size
