SP elite 2.1 material breath at 15K min vs 20K min for other waterproof-breathable materials like nanopro and dermizax nx but the SP elite jacket has very good venting so it probably close the gap with other w-b with less venting. Vs a jacket that would have as good venting the SP elite jacket would look pretty much out of date in terms of breathability though. Something to look at.
Here is a comment found on MEC website about the SP elite 2.1 jacket

But with this jacket I am usually pretty comfortable in a temperature range of -5 to +10, which covers most of the Victoria winter. At temperatures of +15 or above I would have to wear this jacket wide open or dial back the effort.
