I long ago gave up on rain gear. IME - None worked well enough to justify the cost. The better stuff DOES work better, but the price is also higher. My main objections for commuting purposes is that it's too cumbersome to carry with me on the possibility of rain, and too expensive to buy 2 sets, to leave one at each end. Plus IME most of the not super pricey rain gear doesn't hold up well. (Doesn't include super pricey stuff becase I never tried any).

So, after experimentation, I've settled on 30qt tall trash can liners. These are cheap enough to use once or twice then discard, light enough to carry on spec, and easily deployed at both ends for surprise rain storms.

I should add, that they don't actually keep me dry. Since they don't breathe, my sewat tends to get me pretty wet anyway, but it's the difference between wet and cold and wet and warm.
