These are good for riding in weather down to maybe the mid-40's. Anything cooler than that and you're going to need liners underneath. The fingers are very long which causes a strange fit and a loss of dexterity for shifting. The fingertips themselves, being made of a different material so you can use touchscreen devices, and very little wind resistance, so the faster you ride, the quicker you'll go numb. I will note that the touchscreen interface does work even when layering touchscreen liners underneath, so that's a plus. I've successfully done a ride in the mid-upper 30's using these and some liners. In all, not Pearl iZUMi's best.
