Are park gloves warm enough for midwinter riding?

For active park riding in moderate winter temperatures (15-30°F / -10 to -1°C), yes. The high-output nature of hiking features and hitting jumps generates body heat. However, on very cold days (below 10°F / -12°C) or during long, windy lift rides, park gloves may not provide enough warmth. Consider adding a thin liner glove or switching to a warmer all-mountain glove on the coldest days.
