I appreciate any advice for me, a recent practitioner of wet shaving who is about to deploy to Afghanistan. I will not have ready access to hot water, will shave outside in winter weather (although it probably won't freeze and will reach lows of mid-30's), and will face other obstacles to wet shaving. I use an injector, and have for many years. However, for deployments, I typically use the three blades due to their convenience. Any suggestions on how to continue wet shaving in some form or another in relatively austere conditions? Thanks.
