Make sure you stay warm in your sleeping bag after a long day of hiking by stashing an extra pair of socks in it before you even leave on your camping trip. A little foresight while you pack your gear makes sure your toes will stay toasty all night.

Especially if you go camping during cooler months, doing everything you can to stay warm can prevent you from shivering through a miserable night. Pack an extra pair of warm socks inside your sleeping bag so that you only use them when you sleep.
You probably already pack extra socks in case your feet get wet or dirty while you're hiking or enjoying the great outdoors, so toss a pair in the bottom of your sleeping bag now, before you leave, so you don't use a backup pair just to stay warm. If you've got a water bottle, fill it with hot water and put it at the bottom of your bag too, to amplify the effect of your dry socks.
