We recommend dressing in layers and having options in your bag. Our windproof and waterproof DrymaxX jackets and pants will protect you in harsh conditions, and with mid-layers, you can adjust the warmth of your outfit. A polo t-shirt is a good start, and you can have a mid-layer for warmth and a waterproof & windproof DrymaxX jacket that can be worn when needed - many of our DrymaxX jackets pack down into small spaces! Waterproof shell pants are also easy to add on top of shorts or chinos when the rain comes down pouring.
