I've used my Tamrac 5788 all over Asia and Europe. It's not waterproof but has a rain cover. It has a protected insert area for notebook and can be used backpack or sling style making it very versatile. The top pocket is kind of funky - basically open area with a small mesh side pocket - but it Good for phones, snacks etc when traveling. I've been caught in downpours in Italy without the raincover and my kit was completely dry. I use a ClikElite for local trekking - it has a stabilizing bar on which I've mounted a ballhead and use for Canon 100-400L.
