I started wearing them last spring when the temps in the morning would dip down around 30 degrees F. These gloves are amazing. The material on the back of the gloves is stretchy and breathable yet kept my hands warm all riding season in Wisconsin. The material on the palms of the glove is suede with a grippy pattern "painted" on it, as shown here:

I even continued to wear these when the weather warmed up. They are thin enough to use as liners in heavier gloves too.
