I can definately feel the airflow from the top vent when fist closed.l.
Actually the new Speedmasters top vent is mostly for looks, at least mine are.
I had a pair of the Old Speedmasters with vents on top of each finger. The ones with chrome knuckles. Those glove spoiled me a bit with great airflow. I'd have to peel my leathers off but may hands would be dry.
I finally wore thru the palms and had to pick up a new pair. I looked for another pair of gloves with the finger vents but couldn't find any. The new Speedmasters had that big vent on top of the knuckles so I figured that would work well.
Down at RA my hands sweated a bit so I took a razor blade to the opening of the knukcle vent and made it larger.
Still didn't feel like it was flowing much air so I took a pair of needle nose and pulled the foam out from under the vent, when I did guess what, ...
No vent holes .
The holes in between the fingers work pretty good but don't keep my hands as cool as those older JR's.
Maybe mine are missing the vent holes under the knuckle protector, but I'm pretty sure its just a fake air inlet.
I vote for Vented and un-Vented. Use the right glove for the appropriate temps.
