I too keep most stuff in a a back pack....and so far only have seen 1 other reference to my other option: Cargo Pants! The side leg pockets are at the perfect level for easy access. You can cram alot of stuff in there without interfering with your hunt, hike, whatever...and nothing gets tangled in your packs straps.
You can find them in any camo pattern under the sun--esp. if you check out the military surplus type catalogs; but I've found some really good ones at Goodwillm for $2's !!
Another point that might be helpfull: If you use a backpack with multiple pockets and your basic stuff is always the same: keep them in the same pockets always, no matter the season! That way if an emergency hits and/or night falls before you're out of it---you won't have to search for your stuff--in a panic situation, it's amazing how you forget where you stashed your first-aid kit or extra batteries " the last time you put them in there". Keep it simple--keep it consistent! JMO!
