This is by far the best jacket I've ever had. Living in Poland - home of heavy rains, snows and deep freezing temperatures...this jacket simply kicks ass! Although it's pretty "thin" and light, it's by far the warmest jacket I have. I do lots of walking/hiking and it keeps me 100% warm and dry. If it becomes too hot, simply stuff it in your day pack, or pack it away in the on board stow away pouch. It is well worth the money, and I highly recommend this jacket you'll be glad you did too. I rarely post, but think this deserves spreading the word.
