I like anything that alpinestars puts out, especially boots. I also have a pair of armoured GP Pro gloves that rock.
Spidi makes good leathers, as does Dainese.
And IMO, nothing beats Arai Quantum helmets. Most comfortable helmet I've ever put on my head.
Stay away from Joe Rocket stuff. It's total crap. I bought a vented jacket that came apart at the stitches, literally. And it was only 3 weeks old. Plus, while riding with it on, the collar would rub on my adam's apple and really make riding with it really unbearable.
Edit:
if you want the best in the biz, you can get custom leathers here:

I used to live not to far from there. Helimot is a really friendly guy. But take your checkbook and don't be afraid to use it. Pricey, but there is a reason a TON of pro racers use his stuff. It's the best in the world for the average joe.
