I've tried Paramo for a while now. I really want it to work! I bought mine cheap from the Paramo 2nds store, but they promised me that it was fully functional.
I've used mine a lot! It really is comfortable, breathable, non-crinckly and - most of the time - keeps me dry. I use it around town, and i use it for day trips in the forest if it isn't too warm. (Here in Norway, that gives it a season of about 10 months...). It's versatility means that could replace several items in a normal system. It's great to walk
But I've also just bought a RAB Newton. Why? Because on two or three occasions, the paramo-piece has failed properly, leaving me absolutely soaked. Now, apparently the reason for this might be that I haven't been careful enough in my tech-washing and re-proofing. But I've tried my best, washed out the soap in the dispenser and all. I figure that if that effort isn't enough, then it is too sensitive for my needs. I'm not going to buy a new washing machine or anything.
Which leaves me with the conclusion that I can't really trust it for serious backpacking. Sad, really. It is so close to being the perfect shoulder season gear!
