I have to respectfully disagree with the person who said these run very small (at least in the small/medium range). My measurements are 12" at largest point of my massive biceps, my wrists are 7". Right between small and medium.
I've owned these in medium and gave them away because they seemed a little loose for my taste and seemed to be a little baggy/wrinkled at times.
I now own them in small and they fit perfectly for what I want. You have to fiddle with them to get them on but they aren't tight but they aren't wrinkled either.
These are great lightweight gloves that like most Castelli products run slightly small.
I frequently use Pactimo products thanks to their discount program, but gloves are an area where their product is average. These Castelli gloves feel to be well manufactured, having survived multiple washes with no fraying threads, loss of color or cushion, incredibly breathable, mostly minimal padding (I strictly want gloves for sweat wicking). I love my Assos rsr gloves and I would say that the Castelli offering are a close second to them, and POC gloves a very close third. I will almost certainly buy more of these, unless those Assos rsr speed gloves go on a major sale. If you want thick gel gloves, these are probably NOT meant for you.
I live in the dry climate of Southern Colorado and almost immediately first ride I realized this was the wrong glove for this area. There is almost zero breathability your hands will get wet and stay that way this is made to keep your hands warm when wet like a wet suit it's the same material.
They kept my hands warm, but it's such a drag to have wet hands for no good reason. I could not wait to get these off and have never worn them again.
I bet they work great in the rain doing their job exactly as intended. Maybe it's a versatile glove for San Francisco Bay area climate, but I lean on this being a specialty glove only useful if it might actively rain during your ride.
Had higher hopes than what I got. For starters, I expected a glove that had "arenberg" in title to have thicker padding. I have a pair of corsa rosso road fingerless gloves and the padding between to two is a bit similar. I had bought these with the purpose of using them cool weather gravel. To that effect my dainty hands were not quite as comfortable as I hoped. Another shortcoming is the snot strip. It's suede rather than fleece and thus not very good. The grip is decent but they made no effort to add touch screen compatibility. Considering how bike computers are heading in that direction whether we like it or not this would make it tough to adjust things let alone check your phone without taking off your gloves. I'll give these gloves credit for being gloves and better than nothing for shoulder season. I'm hoping as they break in the sharpness in the fabric between the thumb and first finger will soften.
