Here's the thing - Cork is really, really tough stuff. Perhaps not as tough as 1050 denier ballistic nylon, but still very tough. We wouldn't use it if it wasn't tough. While no official cold weather experiments have been conducted on cork, I've used Cork Organizer Pouches and my Archetype (in Cork) since 2006 in Seattle weather, and other than the natural darkening of the cork, there's no change in it. We've sold Cork bags since 2006 to customers all over the world and haven't heard of any complaints or problems from customers.
When we first began using the cork fabric, we did tie a Cork Organizer Pouch to the bicycle of an employee who biked to and from work everyday in all kinds of Seattle weather (including snow), and other than that natural darkening, it was as good as new.
I hope this helps!
