The vest is lightweight and good for trail running. I've used it for day hikes but it is a little lightweight for what I feel are essentials for cold weather. When you load it up as advertised its pretty hard to conveniently get into the side pockets. I also have concerns that it will hold up with a lot of use. With a little over a months use, some of the stretch pockets are getting too loose. Time will tell how the seams / stitching hold up. Don't expect to carry a lot of weight in this vest.
