Paramo is very good at breathable, but it's bulky to carry when not being worn, and is warm enough to be problematical in summer (like putting on an extra jersey plus windshell).
Shakedry is lightweight, compact (jersey pocket size), black, and breathable enough to use as a windshell at a fairly decent pace. It's also fairly delicate. You'd be lucky if it survived an off, and you'd want to be careful about brushing past hedges etc that may have thorns.
Regular non-shakedry waterproofs can be almost equally good to start with, but if the rain lasts too long (where the duration of "too long" depends on how new they are), they wet out and become non-breathable, and wet from condensation inside.
I've found rainlegs inadequate for more than a couple of miles. They are full of stitching holes, the rain runs off the edge onto your trousers, and air doesn't circulate over the top of the leg so sweatiness does accumulate.
I use Shakedry (patched where the thorns got it), and goretex shorts. Knees down is skin, which dries quickly.
