Very nice top. The windstopper is a great feature, so too the reflective piping and logos. I purchased the small as per all my clothing these days and it fitted fine. 2 slight improvements: 1 - The forearm part of the top is just big enough for my forearms. Maybe a bit of lycra here would help cover the range of wearers. 2 - the neck is a very snug fit when zipped right up. Snug to the point of too snug. Apart from the above points, it is a very good top (although I give it a good rating!)
