I use Neoshell in the winter when I expect it to be wet all day.
It’s thicker and therefore warmer than Shakedry. IME it’s about as waterproof and breathable as Shakedry which is high praise as that’s excellent. It’s stretchier, warmer and less ‘clingy’ for all day wear. I also think it’s a bit more robust than Shakedry.
They are the only two flavours of breathable fabric I’ve had that are actually waterproof and very breathable. I’ve had most of the Gore Tex iterations, eVent and a number of the ‘copies’ once the copyright lapsed.
For my cycling, I need both but choose which dependant on the day.
