Nice to see how you bug out bag starts to take shape
Here are a few tips, about what I think, your mileage may vary
* You don't really need the tent nor the sleeping bag, or just carry the sleeping bag if is too cold.
* You are carrying the 2lt camelback, a nalgene and a 2lt canteen and you're planning on getting another canteen? Why don't you get a water purification device?
* I would change the baseball cap for a boonie hat that will cover better the back of the neck and ears.
* You can discard the axe and the shovel, too big and heavy, you could use a "pocket chainsaw" instead and fuck the shovel
* Get a headlamp, they are extremely handy.
* You'll hate me about this one... but why don't you change your revolver for a pistol? More bullets and quicker reloads are really handy, specially if you plan to go solo.
Also, and this one is very important, grab your bag and walk with it, walk a lot and you'll notice how you regret of each extra gram you put in it.
