It may seem like a silly question, but what do you plan on wearing for the apocalypse? Your clothing will be your first line of defense against the weather. Heading out in a snowstorm wearing sweats and flip flops would be a serious mistake. Your bug out bag is important, but you also need to put together the outfit that will protect you and aid you in your goal to survive whatever has come your way. There are some key components to look for when you are putting together your survival outfit.
Getting wet could kill you in a cold weather situation. You want to stay as dry as possible. Even though it may seem like a good idea to get wet in a hot weather situation, you would be very uncomfortable and your skin would chafe. Duck canvas pants are a good option. Gortex is nice, but it will tear with just the slightest brush of a branch or rubbing against a jagged rock.
Again, the duck canvas is a nice choice for pants at least. It is very durable and isn’t going to shred while you walk and climb over rough terrain. It is actually fairly comfortable as well and will get more comfy once you break in the gear.
Even in warm weather, nights can be very chilly. A jacket is going to be a nice addition. The jacket should have a wool or fleece lining to keep you warm. An outer shell made with a breathable material will keep you from sweating. Many of the hiking jackets you will find have several layers that you can remove or add as needed.
Pockets are awesome. Cargo pants are worn by the military for a reason. They can pack around a great deal of gear on their person. It is much easier to get to something in a pocket than it is in a backpack. Tactical vests, pants and jackets should definitely be included in your survival wear.
This is the layer of clothing that you would wear under your shirt or pants. There are a lot of choices in this area. The weather you are preparing to bug out in will play a huge role in deciding what to pack. Make sure you update your outfit with the season. Merino wool tends to be a favorite for cold weather situations. Silk is incredibly soft and adds a nice layer of protection for the skin in cold or warm weather situations.
