What Our Gearhead(R) Experts Are Saying:"I wore the Dendrite Single Neck Tube on a cold lift heavy day and it kept the wind off my neck without ever feeling damp from sweat. Simple piece of gear, but I notice the difference every time I forget it at home."A cold neck can ruin an otherwise great day on the mountain, and the Dendrite Single Neck Tube keeps that from happening without any bulk. It traps warmth right where you need it, while moisture wicking properties keep sweat from turning into a chill on the lift back up. UPF 50+ protection adds a layer of defense against high altitude sun, making it as useful on bluebird days as it is on the coldest storm days. Made from recycled plastic bottles, it's a small piece of gear built with a bit of care for where it came from.
