I'm starting to put together a GHB for my wife to keep in her car. I estimate it will end up being about 15 lbs. What are you guys using for the actual bag? She told me she had one, then produced a Barbie-pink book bag. I had to explain to her the benefits of being discrete.
I'm looking for comfort and durability.
Dependant on your budget you can go two routes.
#1 Civilian Backpack (I like osprey and REI bags for the suspension and ease of carrying)
#2 Military: These are great bag systems but draw attention....if your carrying a maxpedition bag chances are your carrying a gun (Criminals know that).
Here is some good places to look.
www.countycomm.com these are good military bags
www.geartrade.com consignment shop for used outdoor gear.
PM me if you have any further questions.
