For the past years I have always uses a synthetic brush for traveling; most recently the Muhle "turn back" models with STF (V1 and V2) knots.

They are nice brushes. The primary reason I acquired them was due to the fact synthetic knots dry so quickly and are pretty much maintenance free.

I recently came across a Dovo travel brush which looks interesting for sure; it has a silver tip knot. Now I know natural hair brushes are used all the time; my question is just HOW much more effort is required to take off for a couple weeks with a badger vs a STF synthetic brush in the kit??
