I've a pair since last summer. At the beginning, you really have to break them in before it get comfortable, cause with their new "injection-molded PU" knuckle system, it was kind of hard for the my pinky finger at the beginning. Once it broken in, it's really nice though. :yesnod Also, the GP-Pro has the "ram-air" type of ventilation system, which is really great for the hot weather, you can feel the air flow sometimes.
