Size: I had Spidi STS-R gloves and also checked the sizing table so I ordered the same size (S). Generally good but the thumb finger tips do not provide much space. This is especially a problem for the right hand when you roll the throttle. I hope the gloves are still breaking in (after 4 days).
Warmth: Not a winter glove. Not a summer glove (above 25C). I don't think the vents at the knuckles are working.
Good protection all around. Not tested (thankfully) judging by the looks.
has a wiper but it is quite small. didn't have the chance to try
