I have a backpack that I often wear on my (outdoor) walks to and from work each day. The walk is 30 minutes one-way and mostly in an open field/park area, so in the afternoon it's usually warm enough that a great swath of my back gets incredibly sweaty from the backpack resting directly against my back.
Is there some accessory or relatively simple modification/method to keep the pack from resting directly against one's back?
I've thought that something simple like a small, partially padded rack attached to me or the pack such that the bottom of the pack is pushed out and away from my back would suffice, as long as my pack was stiff enough up and down the back-facing wall.
I've tried to do some online research into what such a thing might be called, but the closest thing I could find was an unnamed and integrated part of some fancy new backpack that I don't want to have to buy.
Needless to say, if I found a nice solution for this I'd use it each and every time I go hiking, too.
