I use boars & travel quite alot. I take two brushes and keep them in a small tupperware when in the bag/travelling. I dont seee the need to use a different brush when travelling. Some home comforts are a must....

After my last shave I run the brush under a hair dryer to remove the majority of the moisture before putting it in the tupperware for what could be a two hour or two day journey. Never had any drama's.
