Sub Zero thermal undersuit (superseded by Factor2 suit), £89.99
Miles covered/time: Many, many thousands in 10 years.
What’s good? The fact that this suit is around 10 years old but is still just as good as it was when new at keeping me warm during the coldest of winter rides. This really is essential winter clothing which combined with good quality Hein Gericke winter gear is just about impervious to the cold. Wicks sweat away, washes and dries quickly enough for you to give it a rinse in a hotel room sink and still have it dry for the next morning. A brilliant bit of kit all round. Incredibly, I still fit into it 10 years down the line.
What’s not? It’s a little bit thicker than some people might be used to but that’s it.
