I wear the Avenir full-finger gloves down to about 28-27 then switch the the PI Lobster Claws. I've had great success with both. The coldest I've worn the Lobsters in was 12 with a wind chill of 6. Another forum I belong to has those crazy ppl that ride in subzero temps and they keep recommending the Specialized Sub-Zero Gloves. Not a clue what they cost but these guys have worn those with temps down to -Ungodly and swear by them.
