We're well aware of the additional hardships and discomfort associated with riding during the winter months. We certainly don't want our apparel to be our excuse for not getting out, so if you're in the market for a thermal jacket that offers excellent protection during times of precipitation, take a look at the Women's Alpha ROS Jacket from Castelli. It blocks the weather, but the outer layer and insulating layer are separate, so you can choose how much insulation and protection you need, even mid-ride.

From working with pros and from other garments it's created, Castelli learned that a jacket with wind and water protection was necessary, but that protection could occasionally be too much. The Alpha ROS is prepared to pamper you with warmth and dryness this winter riding season.

The thermal layer insulates while breathing quite well so you get more of a thermostat and less of an on/off feel.

At the top, simply zip up and head down without teeth rattling or shivering throwing you off your lines through corners. On the plunge down, you'll appreciate the Gore Windstopper 150 membrane. The windproof three-layer, four-way stretch knit fabric with a water-resistant DWR coating keeps wind out and precipitation at bay. You'll want ...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
