I like the off-white Paddy the best. It would be great for the spring & summer. I ordered the tan pocket Paddy & returned it. I didn't like the tan that much. I'd rather have the whiskey or off-white.
I love the blanc color! The tan isn't doing it for me. There WAS a blanc zippy (what you are calling east/west) on eBay from, I believe, a reputable seller if you want the best of both worlds...not sure if it is the large or the medium, but you might check it out.
