I often ride the bike to work. Even with frost. These gloves have served me well this winter. The palms are, as can be seen in the photo, white. That's good if you want to "flash" before the turn.
The material of palms is also quite prone to dirt and breaks down pretty quickly. When cycling that's not the problem, but for hard work I'd put on other gloves.
The gloves are relatively warm in winter. Warning: rain let through relatively quickly.
