I bought a sweet Spidi leather jacket on ebay brand new from Lockhart-Phillips (their distributor) for 1/3 of the price offered by kneedraggers.com. The jacket is of very high quality. They are sized very small though so keep that in mind.
I've been wearing a Spidi Factory Old jacket for over a year and really like it. Thick leather ,good fit , comfy armor. Was kind of stiff when new but after breakin and a little Lexol its like butta. Also have a pair of Spidi Multi pants that I like very much but the zipper isn't compatible with the one on the jacket. Go figure. I am looking to sell the pants(euro size 50) if anyone is interested. IM me.
I bought a set of Norick leathers from the Lockhart Phillips ebay auctions and so far I'm really pleased. They fit me really well and the armor is comfortable. I doubt they would be good for really hot weather, though they do have some perforation. They run pretty close to Dainese sizing, which is right for me since I'm not "big-boned" ;D The Lockhart guys were great to deal with too. I got a size too big and even though it says clearly in the auction that they don't take returns or exchanges, they exchanged it for a smaller size no problem, quick turnaround too. Paul's a great guy over there.
IXS uses the b!tch zipper too. It's apparently fairly common in euro clothes.
A buddy got an IXS jacket and fumbled with the zip for a little while, but like a like a lot of things, you can get used to it. He's now very happy with the jacket. FWIW. He's gotta have 10,000 mi on it.
