I'm not too familiar with performance jackets of this caliber and price range; I've mostly been a softshell guy given my Midwest upraising. I've had some experience with Marmot's Membrain fabric and with the Pertex implementation in the OR Igneo, but that's about it.
I bought the Victorio and used it on a few hours recently snowshoeing in the backcountry around Mt. Rainier. The temperatures were between 30 and 50 °F, with periods of sun, rain, and snow (yup, mountain weather!). Not having used an eVent or any Gore products, I don't have a basis for comparison, but with just a tee and the jacket, I noticed two things:
1) the jacket never felt clammy against my skin like the Membrain fabric does.
2) even in direct sunlight, I never felt "claustrophobic" in the jacket; it didn't feel constrained from a breathability perspective.
When it was snowing or raining, snowflakes and raindrops beaded on the exterior of the jacket with no wetting through.
Wind did not cut through the jacket at all (any loose opens will of course catch gusts). Pit zips were useful but not terribly necessary given how well the jacket breathes. When I started off with more layers, I noticed that with heavy perspiration the jacket didn't seem to move moisture away from skin as well as when I had on only a tee, but this is to be expected and certainly was of no worse performance than with my other jackets.
I'm 5'6" and 130 pounds, and the small fits quite well. Chest is a little loose but accommodates additional layers well; the waist area is a little large for my frame. Hood is quite large and accommodates a climbing helmet more than just a head + beanie.
I chose this jacket over the Jovian for its 70D material (I tend to be hard on gear when I'm using it), but otherwise either jacket would likely serve my needs well.
Other small observations:
- as noted in other reviews, zippers can be difficult to work... but to me this was not a hindrance.
- one side of the zipper stays mostly upright; the other side flaps over. Makes it difficult not to zip up the jacket the whole way
- chest pockets take some getting used to -- not really practical for keeping hands warm, unless you want to walk like a mummy
Overall, I'm quite pleased with the jacket. I'm hoping it's more durable than some of my other ones, but given that I'm now living in Charleston, I'm not sure how much use I'll get out of this. Will keep this review updated when anything new happens.
