Can I possibly comment here because I know a little about this subject. Your options include base layers, t-shirts and then jackets.
A base layer is a thin next to the skin layer for warmth and exceptional moisture-wicking. They are very light and soft and feel great next to the skin.
A t-shirt should be a technical moisture wicking material similar to what you wear in the summer. Choose long or short sleeve based on preference and perhaps based on the sleevs of a base layer.
The jacket is about protection from the wind and the rain. They are also lightweight and should be really breathable to keep you comfortable and not get too sweaty underneath.
You then mix and match the layers dependent upon temperature and conditions. e.g quite mild but rain you might choose top and jacket. Quite chilly air temp but sunny maybe base layer and top.
Hope that helps. Look for ideas and great products on our site: www.lansonrunning.com or just post back if you need more guidance.
