Ors, I can't fault anyone who suffers from gear lust, but for the money you're talking those are high quality packs for mainly keeping your gear organized in something easy to tote if you have to foot it safety.

Then again, you've got me wondering if I've undershot the quality aspect for a car emergency bag. A yearago I bought two daypack/book bags for $5 each. They've held up OK and are a big improvement over what I had, which was nothing. Even with cheap construction I figure they'll hold up OK for the distance I'd need to walk if I had to leave the car. Likely no more than 2-3 miles to the nearest gas station or motel or 7-11 in my suburban sprawl environs.

Maybe your situation is more rural or you're planning on also using the car bags for "real" day hiking. All I can say is I've found emergency preparedness to be an addictive hobby. Yeah, I've likely wasted some bucks starting out with stuff that turned out to be worthless (probably my worst was buying a $1 flashlight) but at least it got me thinking about the level of performance I really wanted out of a specific piece of gear, but at least I had something in hand to test.

Good luck with your selection!
