Never leave home without your jocks! I know some folks like to get sexy with it or go commando but when it comes to your neck when you're up the hill, we do not recommend. Take nannas advice and keep that shiz warm and protected. These bad boys are the perfect thing for the blizzard days, super thin and breathable so they don't ice up, great on the sunny days to stop you from getting burnt but staying nice and cool... Good for every day really. I'm wearing one in the office right now! Treat yo'self team!
