I would have to agree. I bought a cheap motorcycle rain suit from Lidl and with a towel around the neck, one can stay remarkably dry.
I also bought a perfectly good open face helmet at Lidl for around £25, with a full face opening visor, which does everything a full face helmet does, and more, and before anyone says that one should always go for a quality helmet, which they will, I rationalised it out, that my Three Wheeler was safer than any bike, and very unlikely to tip me onto my head, and I was only buying the helmet for comfort and protection, therefore, as long as it comfortable, any dubious lack of strength characteristics were not required for this application.
