D R Harris London アルミニウムトラベルシェービングブラシ（シンセティック毛）

The aluminium handle is so light it basically disappears in my dopp kit, and the synthetic bristles whip up a solid lather even with hard hotel water. Dries fast too, which is exactly what I wanted for travel.

Took this on a two-week trip and it lathered just as well as my badger brush at home. The synthetic bristles dry fast, which is a lifesaver when you're packing up in a hotel bathroom every morning.

The aluminium body takes up barely any space in my dopp kit and survived a drop onto tile without a scratch. Lathers up faster than my old brush and the synthetic bristles feel nearly identical to badger once wet.
