Layers layers layers. It is better to have it and not need it than to wish you had it, with that said in the summer we recommend long pants (jeans or something else that is comfortable), a short sleeve t-shirt, a light fleece jacket or sweater. We provide outer wear gear but if you'd prefer to wear your own, light rain gear is great as well as mud/waterproof boots. Plan on getting dirty. In the winter the right clothing is the key to staying warm. Your base layer should be something synthetic (poly-pro) or wool and a pair of wool socks. Then a pair of "swishy pants" or joggers is good for your second layer on bottom and then a long sleeve fleece is a great second layer for your top. We have the outer wear for winter and in fact will most likely recommend that you wear our stuff instead of your own. We know our gear will keep you warm but if you are partial to wearing the gear you have we can check it when you arrive to make sure it will keep you warm.
