I have been travelling this week, and as such away from my supplies. The stuff in my GoBag does cover the basics - even if my experimental replacement of the Proraso cream with the Rise Shave Gel will have to be reversed - it fails to provide me with one thing I have come to enjoy:
Shaving is not just about getting the fuzz of my face no more. It is at least partly about staring into my shave nook, picking out what razor(s) I would like to use on any given day, then what soap I would prefer given my mood. The choice of soap gives me input on what brush to employ... and when all is over I get to pick what post shave treatment I want to pamper myself with.
On the road those choices are reduced to what I packed before leaving - and while I still get the fuzz of my face, I don't get the full shave experience.
Such is life, I guess, at least while weight restrictions apply on flights.
