I've been through a fair number of gloves looking for something that can deal with the DC summer heat/humidity and keep me connected to my bike. I've tried different manufacturers, different styles, and all have been okay, but not great. They wouldn't dry fast enough, or breath well enough. They'd be good for the early/late season, but would fall flat during the peak summer months.
These gloves (the Lite Summer style) are just what I've been looking for. The palms are grippy, keeping my hands well in contact with the Loam Grips from PNW. And the backing material is great at wicking sweat away from my hands and drying out, even while riding. But these gloves definitely don't retain sweat/water like the other styles. My hands aren't coming out nearly as pruney and water logged as before. The gloves are easy to remove as well after a good, hard, sweat laden ride. Buy whatever size you've purchased in the past, as the "lite" versions fit just like the others offered by Cognative MTB.
If you live somewhere that gets hot, humid, or a combination of the two during the summer months, these are the gloves you need to keep contact with your bars/grips. They aren't as substantial as the rest, so order a few pairs and rotate them through the ride cycles. But they are just what you need for those uber hot/humid rides.
