I've got nothing with core vents, but do have a Vander Ice wall jacket with pit zips.( I won it for 'letter of the month' from a well known outdoors mag beginning with Tra..)
I use these zips quite a lot often in horrible conditions when you would think you needed all your orifices closed (ooer missus!)
When pushing up steep hills even in driving snow or whatever I find that if I have the zips open I get some ventilation without the weather getting inside.
My problem is forgetting to fasten them and then wearing the jacket in simple wet conditions. I remember when my arms start to get wet
