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.
