I picked up an orvis Chest pack for 49 bucks yesterday. It seems awesome and perfect for the stuff that I carry.
I know that Orvis is usually overpriced, but this seemed to be the most streamlined, yet large capacity I could find. All mesh on the back, so water drains when dumped. I can't wait to give it a whirl this weekend.
By the way, I carry the basics, plus I am looking into one of those hydration systems for the back part of this pack. Useful in the Dog Days on the Flats.
I also carry a spool of premade tippets that loop to loop to my butt section. Eliminates the need to make them in a hurry and botch a knot or two.
