Although the winter season is already upon us, we shouldn't use it as an excuse to NOT go hiking. It all comes down to being prepared and knowing how to dress properly. Below is a pretty good video demonstrating how you should dress when venturing out on a winter hike. Although the spokesman doesn't mention it, you should always have an extra pair of socks in your pack, just in case the ones you're wearing get wet. An extra pair of gloves aren't a bad idea either, not to mention an emergency blankets and the ability to start a fire.
