I have some Castelli Prima gloves, which are okay for weather like we're having at the moment, which isn't warm but isn't cold or rainy. If it's any of those three, then they aren't that desirable if I'm honest. However I can see why they're worth the premium price, as they're snug fitting, good quality and warm, even if the material isn't that great and rubs your hands when you go over bumps and doesn't provide much comfort.
I tend to use DHB kit elsewhere which I can't fault at all. Low price, high quality.
Oh, and they work with touchscreens. For a teenager like me, that's a very important feature.
