How to Buy an Ultralight Insulated Hiking Jacket

Getting ready for a hiking trip? Picking the right jacket is crucial for your comfort and safety.

Picture your clothes like a three-part system: a base layer to keep you dry, a middle layer (your insulated hiking jacket) to keep you warm, and an outer layer to shield you from rain, snow, and wind.

Your jacket should also allow your body sweat to escape, keeping you dry inside. Some jackets have zippers under the armpits for extra airflow.

When choosing your jacket, consider features like a hood, handy pockets, and adjustable closures. Don’t forget about the color – pick one that blends with your surroundings or makes you visible, depending on your preference.
