There are basically three kinds of "waterproof-breathable" rain shells: Goretex, eVent, and proprietary coatings. Goretex and eVent are laminated membranes, and offer the best breathability (still very limited of course), and are also generally expensive. Proprietary coatings generally offer less breathability, and are usually much less expensive.
This jacket you linked to is a very expensive proprietary coating jacket. Sort of the opposite of what one would expect. How did you decide on this particular jacket? By the way
Amazon in the USA has it from an independent shop for $180.
Hope this helps.
