I have a North Face Oval 25 for cold weather camping and an Early Winters Gore Tex bivy for lightweight touring and camping. While the bivy is old, it was my only shelter for years and I first used it on my Seattle to Madison Wi. trip in 1979. The funny thing is that it is still water resistant as any tent. As far as the Oval 25 tent, it's big and heavy but strong and weather tight and can stand up in a blow.
