|realized my rainjacket was not rain proof|
Introduce you to my favorite layer for rain, FROGG TOGGS. Not only did they keep me dry, they are poofy enough to not create a sauna inside your jacket. That allows you to be active (backpacking/hiking) and not get all wet inside because of sweat. The con to this jacket, it is easily ripped, but a patch of duck tape will fix it. Since it is under $30. You can't beat being warm and being outside.
The other advantage is the windbreak option. I have been on top of mountains where the wind can truly blow you over, this is just the protection you need. But, if you have the $ money consider buying the Patagonia Men's Houdini jacket which is lighter and packable for wind.
For your pants, nothing beats rainpants. Even when hiking, I love the protection and the safety from damp tundra when we take a break to throw on a pair of those pants. I don't have a huge preference on brands, because I just find what is available at the thrift store.
Trail running, I just get wet. As long as my workout is around an hour. Having the rain is just a refreshing feel. I do like to wear gloves to keep my hands warm if it is chilly like today. Even my feet don't mind being wet, as long as I know I am able to dry off soon, I just embrace the puddles and a rain to enjoy the challenge of it.
If you have a favorite rain gear, add some comments at the end.
