Are these gloves warm enough for winter running?

Yes for active use in cold, dry conditions. They are the warmest ActiveTemp glove, but they are not windproof, so exposed windy runs and standing around in deep cold will feel chilly.

Do the touchscreen fingertips work with a phone?

Yes, the fingertips are touchscreen compatible for phones and watches. Expect basic taps and swipes to work; fine typing is less reliable than with bare fingers.

No. They are fleece gloves, so they handle dry cold and light snow but soak through in wet conditions. Pair them with a waterproof shell or mitt for rain and slush.

How do they compare with the lighter ActiveTemp gloves?

They are double-layered and the warmest in the line, with more insulation but slightly less feel than the lighter versions. Choose these for colder days and the lighter ones for mild cold or high output.

Can I wear them as a liner under mittens?

Yes. The stretch fleece fits under a shell or mitt for extra warmth, and the breathable grid interior manages sweat during hard effort.

It is Outdoor Research's thermo-regulating fleece technology that adjusts to body temperature. In practice it means the gloves breathe during exertion and hold warmth when you slow down.
