I used to call Rukka the Unicorn of motorcycle jackets, because it basically didn't exist for women in this country. It's still difficult to find except at Revzilla.com :)
Although I had heard about them years ago, finding one in person was pretty much impossible and only available through a small dealer in the Southwest.
Now, I have access to all the Rukka! The Orbita is a winter jacket packed with features that you will love if you're looking for a Fall/Winter/early Spring option. I'm liking the fitment, it has a nice balanced proportion, slightly broader shoulders and roomier arms (with adjustments) and a decent chest space (more than enough for me). I'm wearing a 36, which leaves plenty of room for layers without the thermal liner, which by the way is really lightweight. I would like to wear a 34 since it's snugger but the sample is 36! I would say it runs a size large compared to other European brands like Rev'it.
The Orbita is a waterproof, Gore-Tex jacket so you don't have the mesh panels for hotter weather. There are a few vents, but not enough for hot weather I'm thinking. I'm going to give it a go in hot, warm weather and see what happens.
In the meantime, you can find more details about this jacket on Revzilla.
