The Phunkshun Dendrite Single Tube is an awesome accessory to have for the slopes so you can keep your neck cozy and help keep the warmth stay in. The Dendrite was built with moisture wicking properties so it stays dryer for longer if you generate a lot of sweat, while the Anti Phunk Odor Control helps keep the Dendrite smelling fresh especially during high output activities. You’ll have peace of mind knowing the Dendrite was made responsibly with Recycled Plastic Bottles, that’s Phunkshuns way of giving a little nod to Mother Nature and the environment that we all love so much. The UPF 50+ Sun Protection brings the best protection against the sun especially in higher altitude, making the Phunkshun Dendrite Single Tube a go-to for any winter sport.
