I had the whole system - Velez smock, Taiga fleece, Tiempo fleece, Mountain pull-on - and was very keen for a while. Then I got wet a few times and stayed wet and really went off the stuff. I am now back on Goretex or similar, with Ventile for a bit of fun if it is not really pouring down. My beef, in the end, with Paramo's system was :
- very warm in the summer months
- got heavy and baggy when wet
- leaks when kneeling / leaning on elbows or when wearing under a buoyancy aid
- gets wet and stays wet unless you are working hard and your body heat is drying it out. Wine-cooler chilling effect.
- regular proofing keeps the system fairy waterproof, but you never know when the proofing is wearing off. If it starts to leak on day one of a five-day trip, you have got a few wet days ahead of you
- odd hood design - I kept getting a press studded flap in the face
- expensive for what you get
On the plus side, it really does breathe and it is very tough. I think for running or cycling it is probably pretty good, or for just wearing as a soft-shell or mid-layer, if you have a proper waterproof in the rucksack.
I am also still a very big fan of their Fuera windshirt with hood. Superb piece of windproof kit, which I always carry.
