So far these are summer gloves. I only ride 135 miles a week and on short rides will go without gloves. These replace a previous pair of Giros, different model but equivalent. I've used those for three years and they're still serviceable, palm padding is thinner and the back fabric has opened up but neither are real issues I have carbon bars. Fit is, of course, snug for a while. Aside from Assos summer gloves, fine but not noticeably better than the Giros, I've not worn any by other manufacturers.
I usually wear a medium in almost all clothing, but ordered these gloves in large to be safe. They are comfortable and a bit snug. If I had ordered medium, it would be difficult on put on and possibly impossible to take off.
