Give your board some TLC with a fresh lick of snowboard wax. We have flavours for every temperature. Get yourself a snowboard wax iron so you can do it yourself and save your pennies for the aprés-bar.
Hand waxing your snowboard with a snowboard wax iron is the best way to apply it. The snowboard wax will last longer, keeping you fast for the horrible flat spots on the traverses and it'll protect your base for longer. There's also something pretty therapeutic about it.
