Is it Water proof. How will it perform in the rain

This jacket is highly water resistant but not waterproof. While water will not penetrate the body or arms, you might experience some seepage after a while when worn in steady rain as the seams are not sealed and the zippers are not waterproof. If you are seeking a fully waterproof jacket, you should check out the Alp-X jacket as it is made of GORE-TEX® Paclite® which is fully windproof and waterproof. All GORE-TEX® jackets carry the lifetime "Guaranteed To Keep You Dry" promise.
