If you are starting out on a chilly (under 50F morning) and the temp rises later in the ride, what is the best way to stay comfortable. I'm thinking that wearing a small daypck may be the answer where extra clothes can be peeled and stored during the ride. I bought a Fox Huck jacket which has zippered sleeves and can be converted to a vest, to address this issue.
I also bought my first pair of tights, Gore Bike-Wear classic action bibs with windstopper. I think these will be great under 50, but wonder at what temp will heavy-duty tights be too hot ?
I ride in the mountains, so the temp fluctuations are magnified by the exertion and speed differences caused by the terrain.
