Living in Southern California it seems very wrong that I have to even ask this question, but our night temps have been in the 20s, but it's a cold snap, and when it passes it's going to be shorts and flip flop weather again. I know these temp variations are hard for me to get used to, and I wonder if I shouldn't be thinking about getting Goat Coats for the girls when it's really cold.....? What are the benefits? Are there any downsides? Around what temps tire would you suggest putting them on? Im thinking only on cold nights, with them being removed in the morning.... Advice? Thoughts?
