My sac. Large enough for the essentials, but small enough that I do have to be selective with what I take with me. Inside and outside pockets are easy to access and well placed. The strap is nice and wide and I can wear it cross-wise so my hands are free.
Sounds perfect, right?
But, it seems the strap is warping my shoulder out of place. So until I can move my arm again, I need to see other bags. A trial separation.
