Do not normally review items, but felt I had to in this case as a warning to others. Other Lifa tops I have are in a Large size, and are, if anything slightly too big. That's OK as I do not like them to be ultra-tight (shows off the belly too much). They are slightly long in the arms, and have a great back length which does not ride up when cycling. Not so the Charger. I bought an Extra Large as I had heard they might be slightly smaller. When it arrived it was barely big enough. Just about OK in the arms, but the back length was pitiful. For cycling, and presumably other active sport like skiing, absolutely useless - unless you wear another base layer as well, which pretty much defeats the object. So, if you are set on a zip at the neck, buy one at least two sizes bigger than normal or just don't bother. Me, I will not be bothering again, and will go back to the normal Lifa tops. Feels like Helly are skimping on materials to shave a bit more profit. Expected better from them. This review does not reflect on the service from Amazon and the supplier of the top, which was as I ordered and prompt.
