Too hot or too cold? One of the key things to enjoying a day out is staying at the right temperature. This insulated vest does just that. It keeps you warm enough for an active day on the trail. You can wear it with a tech tee on a dry day or under a waterproof when it's raining. We've made it lightweight so it won't weigh you down and packable so it doesn't take up too much space in your backpack. It's all about maximizing your enjoyment, all year round.
