I have acquired a variety of pots and pans over the years, so I generally select a good size for the trip and the amount of cooking I wish to do, which is typically pretty basic (boil water - add stuff - eat).<br><br>When I pack my gear, I put a fair amount of effort into filling the interior of this cookset efficiently. I really don't care whether it mates with the water bottle or not. If it packed full, it is not wasting space in my pack.<br><br>In my opinion, all those water bottle holders, etc. on those cool daypacks and fanny packs are just style and window dressing. In really rough and brushy country, you need a sleek silhouette and a pack that is smooth and tough, the better to slip through the chaparral. All that fancy crap just hangs you up.
