Yep. The "60 degree" mark is an average. I see you're from the same area I am, so you know the last week or so has been really cold for this time of year. We had such a mild winter, I was expecting a dry, warm spring. But nooooOOO! ;D
Yes, Columbia gear is a little more pricey than cheaper stuff, but the quality is there and they last forever. The shirts are what I get. They're very comfortable and keep you cool and free of sunburns. Just hope I get to use mine sometime. :
