I have two pair of full finger perforated leather summer gloves. One pair is Sedeci/CycleGear and the other is sold by Harley. I like them both, pretty much equally. I wear a size 3XL Glove, so just finding any glove that fits comfortably can be something of a challenge. The Harley Gloves are a bit easier to get on and off because the wrist closure is Velcro. The Sedici's have elastic that is sewn into/between the leather and the glove lining. I got the Harley gloves when the local dealer haf a 20% off sale so I actually paid $56 for the Harley gloves and $40.00 for the Sedici's.

He posted about gloves? I couldn't get past his avatar.

 

I've have had a couple pairs of the leather perforated gloves. They keep the back of your hands cool but do nothing for the palms, even though they have holes in the palms. They have double thick leather and no air will pass through as the holes do not line up. I guess that is to insure that your hands are protected in a slide.
I found some textile gloves that have holes in the palms and they actually ventilate all your hand. They are made by Mechanix Wear...While they probably won't protect you hands as well as leather, they do offer protection and ventilation.
BTW They are in the tactical line.

 

I wear these Mechanix brand work gloves in warm weather:

I wear cheap motocross gloves

 

I wear Mechanix Impact gloves most of the year.

 

Lee Parks DeerTours. Probably the best summer gloves out there....

 

I have a few pair of Army nomex flight gloves that i use in the spring, summer and early fall. leather in the palm and the rest is nomex.

I saw black flight gloves in the miltary sales section of the px for 18 dollars and i bought two pair.

They won't provide much protection if your skidding along the ground, but they give me a good feel on the controls and provide some protection and i don't cause my hands to sweat.

These are similar:


Not the sexiest gloves but i had'em on hand and when they had a sale, had to get the black ones.

 

I have a pair of perforated deer skin gloves and a pair of old, worn out Wells Lamont work gloves with the fingertips cut out. That pretty well makes up my summer choices.

 

I tried not to notice...
