I often work with mixed media (india ink, watercolor, colored pencil, alcohol markers, gouache, etc) and this sketchbook has been perfect for me. The pages resist multiple layers of wet media and the texture is really nice for colored pencils (I don't recommend using both sides of a page though, at least not if using wet media or markers). Alcohol markers do bleed at certain point, but the sketchbook comes with a soft plastic sheet that has been an absolute life saver as it prevents you from accidentally staining the pages under your current drawing or leaving undesired marks on them while drawing if you have a heavy hand (like me). Besides that, the sketchbook has hard cover and a paper pocket in the back. I'm very happy with my purchase.
