The Scott Cascadia is a Gore-Tex softshell that is at the top of their offering line. It's a technical shell-style fit, so if you're looking for a park-style piece, go elsewhere.
Where it shines is in it's waterproofing. The Gore-Tex softshell material has held it's own in every single weather event I have subjected it to, including pounding rain and heavy, wet snow. It's a solid 3-season rain option as well. Generous venting is available on each arm (this is also a drawback, more on that below) and the jacket's breathability is very good. The softshell fabric has a nice feel as well with it feeling sturdy and solid.
Where it falls short is in it's features. For the top of their line jacket, Scott skimped on the features bigtime. You get three pockets: two hand pockets, and a chest pocket (actually - it looks like Scott has done away with the chest pocket on this years Cascadia, moving it to the arm. This makes the pocket less useful in my opinion.). The underarm venting does not have mesh; this works great for dumping heat, but it also makes it impractical to have the vents open when skiing. Want to carry your media player/phone for some music? Better hope that your baselayers or midlayer has a chest pocket. The Cascadia lacks a media pocket. Like wrist gaitors or a snow skirt? Look elsewhere as they are not to be found on the Cascadia.
The lack of features gives the jacket a minimalistic feel and style; just not at a minimalistic price. The jackets durability, waterproof/breathability and fit and feel of the softshell material are a 10. My overall rating of 7 is based on the fact that for whatever reason the technical shell industry feels that no one wants features integrated into their shells.
