Do 700 X 28mm's fit on your bike as they do with most other road bikes? If so, consider Hutchinson Pythons. The tread and belts are ideal for the trails but they are heavier than pure road tires. They have these in 32's also but I'm guessing those won't fit.
Check their website. The companies don't tend to list the cross-sectional height of the tires but they may respond to an email.
