I cycle 20 miles a day and use this as the base layer. When I used it the first time I couldn't believe how initially it kept me warm and then I got this cooling feeling the further I cycled without ever getting cold. Has revolutionised my ride as my times have come down and I don't get the clammyness I used to get. A great product. Bought the long sleeve for the cooler winter rides as well. A great price as well.
Keeps warm in the colder weather, while training.
Good fit, length and weight, not too thin.
