My last Spyder jacket needed replacing after many years of good use. The replacement is a newer version of the same jacket, and many improvements have been made: (1) it's lighter and thinner; I was suspicious at first that it wouldn't be as warm as my last jacket, but my concerns were not warranted; it's just as warm! (2) the zippers on the side pockets (which broke on my previous jacket) were replaced with something much more durable; thank goodness, as I use this pockets alot. (3) already took them out skiing, and they are fantastic; good movement all around. Thanks for the upgrade!
