If you will be hiking in a damp environment like the Pacific Northwest than gaiters can help keep your legs dry and water out of your boots. When it comes to your hands two layers also work best. An inner layer of a glove, preferably of a light and thin synthetic material works well. Even natural wool can provide you good protection. The outer shell should be a mitten.
Mittens offer more insulation than gloves and provide more overall comfort.
When it comes time to use your hands you can remove the shell while keeping your skin protected by the inner glove. Gore-Tex and treated synthetics are best for a shell, but can be expensive. If your hike in the winter is going to require you to swing an ice axe then a glove shell will offer you a better grip.
