i always think that breathable stuff only works in super cold weather. One of my mates does a bit of kayaking so i purchased a set of wet suit bottoms yes my legs get wet but they stay warm.My wet weather riding is a Endura stealth jacket,Kayaking trousers and seal skin socks/gloves duct taped to my legs at the top.The only downside to all this is it gets hot okay on the road but roasting mtbing
