I just received these gloves and i must say i am impressed!Nice looking gloves.
Now,as for the technical details:
-they do have a nice thin layer of leather(perforated at some points)reinforcing the palm and also the area between the thumb and index finger
-the area between fingers is made of some elastic material for better comfort
-the back of the hand is made of three different materials(as seen in foto)
-there is a velcro tab so you can close it to your liking
-they have a nice slim fit(at least in my hand)
-they have a good grip with the bike
Keep in mind is that these are not winter gloves,so i wouldn't recommend using them for cycling in the cold.
Also,i would recommend using the sizing chart from the manufacturer's website,to avoid mistakes.
So,as far as i'm concerned,recommended!!
