The Montane Duality Mountain GORE-TEX cap is light and waterproof year round addition to keep you warm and comfortable in cold, wet and wind weather.  The cap is made of 40-denier GORE-TEX Performance Technology, which makes it waterproof and windproof but still lets air through for active use.  With a stiffened peak it helps keep rain or low sun out of your eyes and with integrated ear flaps protects your ears from the wind and cold, which is especially helpful on exposed ridges or just when out walking in the winter.  The cap is lined with a soft microfleece keeping your head warm and cool by wicking sweat away from your head.

The cap only weight around 45 grams, so it easily fits in your pocket or inside your backpack and comes with an adjustable chin strap to help ensure it won't blow off during strong winds or when moving quickly.  So keep your head warm and dry with this unisex cap.
