Mosey...the only place Ursacks are out of style is in Ca, in the Sierras. In our hiking group we have over 20 Ursacks, some dating back 8 or 9 years old.
My going on 7 year old one has seen a hundred trips maybe? Still works like new, just has a funky odor from overuse.

And don't forget: while the odor barrier bags work, they only work if you have CLEAN hands when sealing the bag. Otherwise? Well, it smells like food and isn't much better than a freezer bag for durability!
