I ride in Guam where it is always warm and humid. There's also a good chance you'll get rained on. I bought these gloves because I prefer the deerskin since it doesn't "bleed" when it gets wet. These gloves fit good and are real comfortable, no seams pressing against your hands. My palm is 4.5 in across and the Tourmaster sizing chart said to order a size 11/XL. They fit perfectly.
