For those among us who are perpetually cold whenever the temperature reads anything less than 80 degrees, life is a whole lot more comfortable with some added warmth by your side. From lightweight fleeces to heavy-duty down jackets and everything in between, we've brought together a selection of the best insulated jackets that we could find for your next skiing, hiking, or climbing adventure. You don't have to just choose one either. Feel free to mix and match, layer up, or layer down. It's a cold, cold world out there, so make sure to get the insulation you need.
