We use Klim gear and feel it's the best stuff out there, bar none. Not sure what size? Here's Klim's sizing chart http://www.klimusa.com/f/sizes.html.
Any color you want, as long as it's gray (it's all they make). Large and X-Large sizes are stocked, other sizes are special order so please allow a little more time for shipping.
Here's what they say:
The highly anticipated Traverse Jacket is designed specifically for enduro and off-road riders who demand an extremely durable, waterproof and presicely patterned riding jacket. Highly durable GORE-TEX® fabrics protect you from the elements while drawing moisture away from your body, keeping you dry and comfortable. Built-in ventilation allows you to adapt to whatever environmental condition you face.
