Aldi wet weather gear is getting a work out in Sydney at the moment, costs about $35 bucks, folds up to nothing and is ok, top great,
pants might get something else as water pools in seat and seems to get in, may need just spray with water proof scotch guard for a start or get some shell snowboard pants with high repler water rating like above 10k or 15k
i wear a set of HD lightweight raingear , breathable gortex jacket 100% waterproof, waterproof pants that have an insert so the pipes don't burn them, can also be used on extra cold days over your normal riding jacket to keep the wind out,
cost 180.00. no complaints from me .
