Clothing(Something to blend in with trees.),
Swiss Army Knife,
Extra pair of socks
Every thing will be Explained through the steps.
Step 1: Clothing
Camo jackets are useful in the sense of: their light, have many pockets, Keep you warm during winter, and if you get hot you can role up your sleeves.
Pair of pants. DUH So its harder to cut your legs on any thing sharp and to keep little animals from crawling up your legs at night while you sleep.
Belt, to keep you pants from falling down and you can carry your knife on it.
Socks and shoes(or boots) are there to protect your feet from snake bites and other poisonious creatures.
Also be sure to have a extra pair of socks. I know it sound rediculous but, When you have dry feet and no hypothermia later you'll thank me.
Step 2: Knives
Note: Keep knife away until needed. No need to cut yourself.
