I used this for light frost protection. I'm in south georgia, Zone 8b, so this did suit my purposes. We had one night that dipped to just 32f and the rest of the month was due to be warm so I wanted to protect an alyssum and ajuga bed from the early frost. Its very thin, and is wide thatched and see-through. I probably wouldn't use this any further north as a single layer but it could be used to wrap around tender shrubs etc (more than once) in colder climates I'm sure. The price is a bargain so I had purchased 2.
