I can offer up no reason why my now amply cushioned bum needs more padding today than it did in my boney-assed youth, but it does.
So for that reason I carry in a pocket on my backpack that can be reached most easily, a folded pad or cushion. I actually own a few of these but only carry one at a time. Number two is due to my having thought I had lost number one, but I hadn’t. Number three is pretty much exactly the same but it actually seems to weigh nothing. It cost about £3 in an outdoors shop somewhere in Scotland that I can’t remember where, and that was only 3 months ago. Sigh. So that is now the one I carry. It scores a little less on the “padding index” but you can’t beat weighing nothing. It also is a bright fluorescent green so I hopefully won’t leave it behind.
Here is where they have saved the day. Notre Dame stadium where the seats are just wooden benches (more recently replaced by aluminum, fewer splinters), the Big House at Michigan (benches once again), quite a few train station benches, a few airport seats meant to inflict pain, innumerable wet benches after a rain shower, more wet picnic table benches, a wet and misshapen rock on the Kennebec River (White water rafting in Maine), and finally to give my back some support in bed when suffering a back ache.
It is permanently packed in my backpack’s back outside pocket.
Don’t leave home without one.
