As a four season cyclist, I am often having to carefully adjust my layers of insulation to balance the initial cold with potential overheating. The Champion double dry long sleeve t-shirt is perfect for these precise adjustments as it is quite thin. It is a nice addition under a fleece insulation layer, which is beneath my overpriced Arcteryx jacket. The shirt doesn't retain moisture so when I finally warm up in the middle of a January ride, I don't perspire excessively. If I need to cool down while riding, unzipping the other two layers allows humidity to vent through the fabric and force cold air around my upper body.

On occasion, I will wear this shirt during my heavy free weight workouts. The shirt is so thin it doesn't restrict any motion. Again, it can be used under a fleece layer during the initial part of the workout to warm up the muscles quickly. For early fall cycling, this shirt can be tightly rolled up and placed into a large under-the-saddle bag leaving enough room for a cell phone, wallet and keys.

After a year of frequently wearing this shirt, there are no snags or tears. In total, I have been very happy with my purchase.  This shirt is highly recommended for anyone exercising in cold weather needing a thin layer to tweak heat retention.
