If you ride a motorcycle, eventually you are gonna get wet.
I gave up attempting to keep my hands dry about 45 years ago - and went with keeping them warm instead. Grip heaters are wonderful. Gloves will dry.
My feet are protected by a pair of good quality leather hiking boots, which I waterproof regularly. In a protracted downpour I wear a pair of Belstaff gaiters. They cover the boot from heel to toe, leaving the sole of the boot exposed, and extend up the leg to just below the knee. They are elastisized at the top and fasten with a Velcro strip up the inside of the leg. Remember to put them on BEFORE the rain pants.
For rain pants, I bought a good quality pair of gore-tex hiking over pants. They are waterproof and they breathe. They have a full length zipper on the outside of both legs.
I bought an Olympia rain jacket last summer - but it hasn't been tested by anything heavier than a short but intense shower yet. So far, so good. It has a hood that rolls up in the collar. It doesn't stop raining when you get to your destination - at least it never did for me - and the hood helps to keep your head dry.
Whatever you end up with - go large with the sizing. You're not making a fashion statement - you just want to stay warm and reasonably dry.
Also, an effort should be made to make your raingear easy to put on. You're prolly gonna be stopped on the side of the road in a downpour struggling put it on.
And you just know that as soon as you are all buttoned up, you'll have to pee.
Cheers!
