Fit: Medium; not tight or form fitting by any means, but no need for super-ghetto bagginess either!
Vents: The more the better! Crotch vents are a must, and side / others are definitely a selling point too.
Pockets: Have seen a few pairs lately that are pretty lacking on pockets. I expect at least front and back (zippered) pockets similar to regular pants. Cargo pockets are a plus too.
Insulation: Slight. I don't want a straight-up shell, a little bit is nice but there's no need for tons of big, bulky synthetic insulation stuffed in there. I can layer underneath if it's cold!
Color: Blue or Green. Bright.
I think that's about it. Wadda ya got for me?
