In reply to Hector Heathcote:
Another vote for Paramo.
I currently use a Velez Adventure smock. Prior to that, over the preceding 30 years I had been through PU and neoprene proofed non-breatheable shells, then 4 different Goretex jackets (all from well known major brands). ALL THE GORETEX JACKETS EVENTUALLY LEAKED!
They were fine when relatively new, but the hydrophobic treatment of the outer shell eventually becomes less effective. Once that happens and the material 'wets out', it seems that the Goretex membrane alone, cannot cope and leaks happen. On one occasion this happened in potentially life threatening conditions (the exact time that you need it to perform!).
Paramo is a 'Marmite' brand i.e. love or hate. My experience with the Velez is that I use it differently to a normal shell in that it can become normal wear, even when not raining. However, it is much warmer than a shell, so I tend to wear a merino base layer then the Velez. Ventilation can be controlled to a certain extent via the zips and cuffs, but it may not be the best if you run hot. In my experience Paramo is far more breathable than Goretex. In winter I use the same, but add a thin fleece to the layers and an overlayer when stopped (belaying). I also have Aspira salopettes for winter climbing and love 'em.
So, in summary, Paramo stuff is heavier, warmer and more breathable, but you need to use it differently to other shell jackets to get the most from it.
Just my opinion. Others will differ.
