For years I have tried to find a backpack that I could use for every day school use (College Professor), travel, and day hikes when on vacation. I finally gave up and bought a Gregory Z30 for day hikes to compliment my North Face Recon for work. That got me thinking about my "pack portfolio." I tried searching through the gear thread and couldn't find one on the subject. If there is one, please post a link. If not, or if it is an old thread and could use some updates, please post about your portfolio of packs and their specific uses. I am not talking about ALL of your packs, but the ones that you use. I'll start with my example of what I am talking about.
ULA Circuit – used for 90% or more of my backpacking. Chosen for comfort, design, and ability to carry 18-28 pounds total weight (my range of carry weights depending on length of trip and re-supply).
North Face Recon – used for work (which is school). Chosen for ability to carry laptop, books, papers, pens, etc. Chosen for organization and ability to fit into the hard bags on my motorcycle.
Gregory Z30 – used for day hikes and vacations. Generally loaded with 10-20 pounds…I normally carry my wife's stuff as well as mine. Typically water, jackets, binoculars, snacks, etc. I don't attempt to go ultralight in these cases. Chosen because of size, comfort and airflow…I don't mind a sweaty back when backpacking (I'm expecting to be obnoxious), but on day hikes it bothers me more. Since I have quit carrying a computer on vacations in favor of a small tablet this will share duty with my Recon depending on the vacation.
Gregory Baltoro – a relic from my days of loading myself down with 45 pounds. I keep it just in case I ever see a need to carry a lot of weight on a trip. Think about bringing newbies on a short trip where you want to carry a lot of comforts. Also for a loaner.
