It's been 100°F + for a couple days here in the past couple weeks. I got a polyester jersey (on sale at Performance Bike if you are interested) and it has made a big difference. The only time I really feel hot on the way home now is when I stop. I guess the moisture wicking is doing its job - I am dry as a bone on the bike and sopping wet when I stop at home. I also got lycra shorts which helped with keeping cool/dry below the waistline...
102°F high predicted for tomorrow - Oh boy!
