The best rain suit in my opinion is the Scott Ergonomic Pro DP. The trousers come in black, the jacket in black or hi viz yellow. Trousers are very high waisted, and both are made of a stretchy material that doesn't flap about. Motolegends website has all the info on them. Approx £160 the pair, dear but they definetely work. Gloves wise, nothing will keep your hands warm unless they're heated, like Gerbing or Keis. For outright waterproofness they've got to be Goretex in my book. I'd look at Klim or Held. A good merino base layer will help you keep warm. Mountain Warehouse have 20% off using discount code FROST at present. Their long johns and long sleeved base layer are good which would be 20 quid each item with the discount.
