While most of the points made are solid, I’ve always found that what’s “regrettable” is highly individual. For instance, in one of my longer excursions, I learned the hard way that leaving a basic first aid kit behind was a mistake—even if the call never came. It’s not about following a strict list but about tailoring your pack to the specific demands of your trail and the climate you’re facing. Sometimes a little extra weight turns out to be a lifesaver when plans go awry.
