Fantastic for low rain areas. Used this bivy for an ultralight shelter backpacking through 14ers in the sawatch range in Colorado. This thing kept me warm bivying at over 13,000 feet on Mt Elbert and I found it convenient enough that I continued to use it even when camping near the car. Super compact but not a good place to sit out long storms. In stormy weather condensation will build up no matter what but it dries quickly. This bivy adds warmth and is pretty great but I'd be dubious using it in the north east where the storms can last a while and may not dry out the next day.
