Sure I meant to be funny but “what’s in your ultralight backpack” does not roll as well. While I look at my camping and hiking gear I hate the way I get ready for a hike. I always bring too much or too little. This is not limited to hiking but any time I put my pack together for a mission (all day soccer tournament with the kids.)My newest strategy is one bag per kit… and this is the list of kits?sheltersleepclotheselectronicsfoodcookwaterfirst aid and hygieneI have to think about the shelter, sleep and clothes. Some of that stuff get’s wet or stinky so choices have to be made. There is nothing better than a gallon or larger ziplock.
