I have a GG case with a ziploc tip closure. I really like it but it isn't very durable. The first one I bought only lasted about 3 seasons but I liked it enough that a replaced it with the same thing anyway. The first one basically dry roted and got a few cracks. The one I have now doesn't seem to be doing that at all, so far (this will be its third year) Just bad batch on the first one? Otherwise I really like it.
