I have been owning over 20 pairs of OR gloves since 2010, it is always size L for me, and I have almost always been satisfied about fitting until recently. All the new pairs I've got seem to have an awkwardly long thumb, about 1/2 too long on size L (9). Probably a bad hand template. On the other hand, the Vigor Heavyweight gloves are a replacement for my old PL 400 sensor glove which the sensor finger ripped off over time. They are tighter than the PL 400 and thumb is too long. Furthermore, Heavyweight does not mean extreme cold weather, but simply the thickest version of the vigor. Think of those as a kind of base layer system. They are good for commuting/day-to-day or high intensity activity by semi-cold day. Work best around -5°C to 5°C for a long period of time. Finally, the sensor fingertips work pretty well.
