Like the general sentiment, you can't replace a jacket with a vest. But that's not what a vest is intended to do, and I'd assume the OP knows that. A vest is an option, an alternative, and a layer. I've used vests in conjunction with a hardshell or softshell in lightweight backpacking situations (where ounces DO count). Particularly on the AT in the summer months where temps don't get too cold (~45F) but it's nice to have an extra base layer at night. I would replace a fleece with the vest to save some weight. If you're talking about using a vest in a hunting application, I'd say the weight you will save is negligible.
