These are pretty good gloves, I ride down to the low 40's- hands stay warm around town (lower speeds) not sure about highway. If it's in the 30's I drive my car. I have a naked (no fairing) motorcycle, just wish the gloves were a bit longer.
I had elastic sewn in the (V) section, with my leather sleeves zipped down I had a gap which created drafts down sleeves. This helped but you really have to pull gloves down tight and they will some times come lose, creating that draft again. Kind of a pain, not bad for the price, just not long enough.
