They made legit suits for 2 years, then their contract with Jon ran out and they got real bad.
To my knowledge, heres what they made:
Matt And Trae - this is the setup the Jon rocks most of Ski Porn, the full suit comes in white, black or green, the last being what I have. The material is really well constructed, taped all the way, ect. (My review here:
https://newschoolers.com/web/content/reviews/action/read/id/432/ ) Really good stuff, 15k/15k and has lasted longer than any Oakley I've bought.
Theres also a line of padded down jackets out there. I think they may be called "Trae" as well, but a fe were on Ebay when I snagged my suit. More insulation, less waterproof. They have the big "JL" logos on the arm that the regular Trae lack.
If you do decide to get one off ebay, heres my advice. Go smaller. I got a large, and being 5'10", its larger than I needed. JL should fit you, so a medium would be fine in my case. Oakley can be XL and look good on anyone, but not this line.
As for buying, ebay is your best bet. Check the UK stores, check them often. They are out there, but they're just really really rare. Alternatively, if you offer me about $1000 for mine, I'd consider a transaction. Just be noted, when you buy one of these things, its hard to justify buying any more outerwear.
