Thanks guys - great help - I managed to contact Adam (the "big Cheese" ) at O2, Here is what he said (note he is very honest re duribility....
Our garment, outside of eVENT, is the most breathable garment on the market to our knowledge. It is over 10,000 MVT, and the US Gov't has tested it to be this way. It is also 100% waterproof, its a membrane, not a coating. The big issue with our gear vs. Marmot or others, is our garments are made from nonwoven spunbound fibers. The garment's membrane is on the outside of the jacket and a spider-web like fabric is the interior. It is extremely lightweight, waterproof, breathable, and compact, but it lacks in DURABILITY. It is intended for walking/biking/hiking/running/fishing etc... It is not made for an environment that it could snag or get roughed up, as it would tear thru the membrane.
