Anyway, the secret. Decent waterproof kit, including boots and gloves. Then boil in the bag waterproof oversuit on top, followed by overboots and overgloves. Make sure everything is tight, especially neck and wrist seals.Waddle to the bike, shut the visor, and don't stop. If you stop you will overheat in seconds, and opening anything will inevitably lead to a leak.

It can be done, it is not comfortable, and not practical for most journeys. I don't bother, I tolerate minor leaks.
My favourite one piece oversuit moment was riding for 4 hrs in France in rain so heavy it was bouncing off the tank, up under my chin and soaked the lining of my lid! However I was dry in my suit. Right up to the point I unzipped it just that touch too at the toll both and let a load of water flood into my lap :angry-cussingblack:
I did say 'do not stop'. Stopping for tolls is a guarantee of a leak, either immediately as you found, or 3 miles down the road when you have not quite sealed it up again.

I succeeded just once, until I ran low on fuel with about 30 miles to go. Dry as a bone at the stop, but the last few miles got very soggy.

I dislike full on lined bike trousers, especially if worn over jeans in winter, so tend to use cheap over trousers over my jeans. I've used Richa and the oxford rainseals and both always leak at the crutch in anything other than light rain. I've tried buying oversized ones so they aren't pulling tight, but they still leak.

The best trousers i've had for staying dry was Dainese Dryline but they stopped making the ones I had and they've nowbecome D-Dry and they arent as good.

As was said in the gloves thread, the price of this stuff has gone up but the quality appears to have come down. :roll:

In VFM terms - although both were a few years ago (ok, 35 ish ... ):

- a Rukka PVC over trousers, £5 from shop clearance bin. Never leaked, just eventually wore through

- a two piece set, thin PVC, golfing waterproofs, from the 'Innovations' shop (they had catalogues too). Thin enough to fold up and keep under the seat, fitted over leathers. Eventually melted into one lump, the way old plastic does

Essentially, heat-sealed PVC boil-in-the-bag is the way to go. Then good gloves and boots. Well-fitted cuffs and collar.

Re neck, trickling in, there have been suits with a built-in hood.
Even bland can be a type of character :wave:

Chatting to a mate who's a motorcycle test examiner and he had an interesting take on over trousers. He said take an old pair and cut them into knee length shorts and wear them over your new pair. Very belt and braces but he said as they tend to leak at the seams and the seams won't line up plus you have double waterproofing (kind of) in the area that they are most likely to leak. Sort of makes sense, although will be wearing 4 layers (with pants) at the top so might be like the Michelin man :lol:
