The Double Haul is the chest/backpack I use. It is not too large but large enough for me. There is plenty of room in the pack for a hydration bladder, rain jacket and lunch. By attaching tools to the outside of the chest pack, it leaves a lot of interior space for fly boxes, leaders and tippet.The zip-down fly bench is nice but I prefer a fly box. So, I removed the foam fly patch on the bench, attached some Velcro to a clear fly box, then attached the box to the bench. That way, I can let the bench down, see what is in the box and open it easily with one hand. This is an awesome chest backpack and I highly recommend it to anyone.
