My day pack is a big fanny pack with suspenders. Its easier for me to get to the smaller items like, calls, binocs, range finder, wind indicators, gps, radio, snacks, water, etc without having to remove a pack. We hunt often hunt early seasons (Sept.) and its nice not having a sweaty spot between your shoulder blades when it gets warm. I can tie my coat on top of it after it warms up or loop the whole thing to the top of my pack frame after a successful hunt.
