answer:I’ve never had a “traveling sketch book”, but I’ve owned typical sketchbooks. For traveling, I recommend getting one that is small and light – perhaps a 5×7 or 8×10 size. Make sure you actually get a sketch pad with textured paper rather than a spiral notebook or something similar. For the medium, I recommend using an Ebony pencil, conte crayons/pastels or any other soft lead. These are best for quick sketching and gestures. With regards to a watercolor sketchbook: I also haven’t had experience with this, but I have done quite a bit of watercolor painting and I would advise against traveling and painting with watercolor. It can be messy, take some time to set up, clean up, and dry.
