I was traveling recently (by air) and decided to try a new setup:
Brush: Muhle 21mm STF travel brush
Lather: La Toja shave stick
Razor: Bic Metal (disposable razor)
Post: Stirling witch hazel (sample size), PAA Mysterium Serum
This was the first time using the Muhle travel brush, La Toja shave stick or the Bic Metal razor.
I was pleased with all three.
The Muhle travel brush was a cool design that took up little space and is probably the lightest brush I own. Having the handle serve as the travel tube with an open end for continued drying was a brilliant idea. I found it to be effective as a brush and plan to use it for car trips as well.
The La Toja shave stick worked well too. I liked the scent and that it was not overpowering like some soaps. I liked the small size and not needing to pack a shave bowl. Between the Muhle brush and this shave stick a lot of real estate was freed up in my dop kit.
The Bic Metal razor (single blade disposable razor with a metal safety bar) worked well for my 2-3 day's growth while traveling. I was impressed. I packed a pair of these razors since I didn't know how many shaves I would get out of one and hedge my bets if I broke one/had a bad razor. I think this will be my air travel razor going forward.
I may have to rethink my car travel gear based on this air travel setup.
