Want to know how to most efficiently pack your backpack for outdoor adventures? This short video from Outdoor Research will teach you everything you need to know. Video Transcription: Hi, my name is Matt Amrein, and today I'm going to show you how to pack a backpack. In 2007 I spent over six months hiking the entire Appalachian Trail; in 2008 I spent over 10 days hiking Washington's own Wonderland Trail. The thing I've learned, whether you're hiking for two days or two weeks, is the things you bring along and how you pack them pretty much stay the same. The first thing that I bring along is water. I like to carry my water in a bladder like this, as well as another container like this. It's also going to be the first thing you put in your backpack. Why? Because it's really heavy and it's probably the heaviest, densest thing you're going to carry. This is what my backpack looks like and it has an extra pouch for your water bladder, and then I string the tube through a hole in the side and snap that to a clip in the front. The first thing I put in my pack is the thing that I won't need until the end of the day, so it's the last thing I'll need. It's my bivy sack and it goes in the bottom like this. I put my sleeping bag in right after that. My hiking style is to eat dry over lunch, so I won't need my stove and my fuel until dinnertime. Next thing I put in is my dry sack full of extra clothes. That will go in next; I usually like to keep it aligned upright so I can reach at it at the top of my pack, and also so I can put my food next to it. At this point, I close the main compartment of my pack, like so. Things I like to put in my pack last are things I'm going to be reaching for throughout the day; got my snacks that I'm going to be munching on throughout the hike. So I put those in here, got a pack cover in case it rains so I can keep that handy, got my headlamp for when night falls. And then my map, compass, first aid kit, and the rest of the 10 essentials, which I like to keep in one spot at the top of my pack. At this point, I put in my extra container of water in the side pouch like this, so I can get at it quick, and lastly, I put in my really lightweight sleeping mat. Because it's lightweight, I'm able to put it on the outside of my pack without fear of losing my balance. As you get into backpacking, you are more than likely to develop your own style, but this is a great place to start. We'll see you on the trail.
