Let’s face it, most naturalists tote quite a bit of gear out into the field for a day of collecting, exploring, or simply enjoying the wonders of nature. Even the most ascetic bird watcher, once content to, like John Muir, take to the fields with nothing more than a flask of tea and a notebook, is now ever increasingly likely to be a practitioner of digiscoping and thus has a few extra bits of gear to bring along. Vests are all well and good (downright superb in some cases) but just as often as not some sort of pack is advantageous.
