Thanks for that, not very encouraging though... Looking for a walking/cycling jacket for my girlfriend actually, and having has mixed experiences with GoreTex and eVent I thought of giving Paramo a go. Now not so sure!
I got a Paramo Quito in 2011 for my Spain tour to use as a lightweight walking/cycling jacket. For cycling I only use it in cooler weather as I sweat a lot. The vent zips help, but I find that anything really waterproof steams up inside in warm weather cycling, although the Paramo system suits me better than Goretex or equivalent membrane-based raingear. In winter, I often wear the Quito on days when it isn't raining, which I wouldn't do with a conventional waterproof. As the Quito is lightweight, I don't expect it to last all that long, the cuffs on mine are getting shabby after 4 years of fairly light use.
A Paramo alternative to the Quito for a light waterproof system is their Bora fleece/windproof combination. This consists of a lightweight fleece treated with water-repellent, and a lightweight windproof jacket without liner. Neither is waterproof on its own, but together they seem to work very well, at least for me. I got this combination in January, and have been wearing the fleece most days since (cycle commute, at work, walking). I put the windproof on top only when it is very cold or raining "properly", the water-repellent fleece works OK for light showers. For my needs, Bora fleece/windproof is more suitable than my Quito, but as it is also a lightweight combination I don't expect it to last all that long with the heavy use it's getting at the moment.
I got a heavier and more durable set of Paramo jacket and trousers for my wife for mid-season and winter walking use. I can't remember the exact model, may have been Pajaro or Cascada. My wife also wears the jacket for cycling, so far she has used it up to temperatures of about 15°C, far too warm for me to use something similar myself. The trousers are a bit baggy, including at the ankles, so not really suitable for cycling. But comfortable enough to be worn as dry-weather walking trousers, unlike conventional overtrousers.
An advantage of Paramo stuff over ordinary lightweight raingear is that it can be reproofed just by washing in the appropriate NikWax product. Down side might be that this washing/reproofing needs doing fairly regularly, otherwise the clothing loses its waterproofing properties.
