Rain jacket: there are literally hundreds of them out there-price point matters, then brand/model at that price. Try Backpacker reviews & REI reviews. I like my Marmot in black. It isn't as nice as the one it replaced that had a mesh liner but works fine. Cost varies with source. For high end at lower price search Sierra Trading Post. Ebay/Amazon too. Forget about the color & buy a cheapo, bright safety vest to wear over whatever you have on. In a pinch Wally World for non-breathable "dry for awhile" jacket. The best "regular ones" have underarm vents too which will get rained in on a bike. Basic difference in walking in the rain vs. flying down the road.
