I have their non-breathable jacket and pant, as well as helmet cover.
Before I got the J&G clothing I was wearing cheap crap from Wal-Mart.
The rain pant is awesome. The legs are cut long and have straps at the bottom to allow them to open up so that you can slip them on over existing clothing with ease. The rear is raised a bit and the elastic waist does not pinch.
The jacket fits great as well. Long arms, dropped tail, extra long pit zips, padded collar, what more could you ask for in a sub 50 dollar jacket.
The quality is much better than the stuff I had been using. The clothing is more quiet, though it still has a little bit of swishing sound in it. It is heavier than my cheap stuff, though still packable in my trunk bag.
I plan on using this stuff as my outer layer for winter commuting.
