If its warm enough the best rain-wear is no rain-wear. Nude if your proud, and the law and/or norms allow. Speedoes if you're forced to to maintain legal minimums but still want to flaunt it. Synthetic shorts if you want to maintain a degree of mystery.

Except for completely impermeable rain-wear, heavily coated material that won't absorb any water, HH and others, just about every sort of rain-wear benefits greatly from the use of a Durable Water Repellent(DWR).

Barrier coated synthetics, with waterproof coating, either breathable or not, on the inside becomes sodden and clammy if the fabric soaks up water. Even if they don't actually leak. Even high-dollar Goretex is pretty miserable if it stops shedding water. IMO if the repellent gives up I'm almost always better off with a fabric with the a completely waterproof coating on the outside.

In fact water repellent is so vital for comfort that highly repellent fabrics are as comfortable and effective as items that have membranes. Or they are as long as the repellent coating keeps working. There are even a few repellents that work on poly fleece well enough to make them effective rain-wear for light and misting rain. At least one brand will do the same thing for cotton. I once treated a tee shirt and it kept light rain off for a couple of washes. A self-defeating item for really cold weather, wet cotton is not your friend, it was an interesting variation for tropical conditions.

Of course how you define "active" makes a lot of difference. Walking with a light pack over flat ground is active. Humping a pack that weighs half your body weight up a steep hill while hacking a path through dense vegetation with a machete is another level of active. I've never seen any breathable membrane that could keep up with the second case if to kept it sealed enough to keep all the rain out.
